Mn13Cr2

Baja Mangan Paduan Kromium

Standar: ASTM A128 Grade C (Cr-bearing) · GB/T 5680 ZGMn13Cr2

What Is Mn13Cr2?

Mn13Cr2 adds roughly 1.5 – 2.5 % chromium to the standard manganese composition. The chromium raises yield strength and wear resistance while keeping the toughness that manganese steel is known for, making it a better all-round choice when impact and abrasion occur together.

Kimia Khas (% berat)

Karbon (C) 1.05 – 1.35 %
mangan (M N) 11.0 – 14.0 %
Chromium (Cr) 1.50 – 2.50 %
Silikon (Dan) 0.30 – 0.80 %
Fosfor (P) 0.070 % maks

Kekerasan

Khas 200 – 250 HB sesuai ketentuan, with a work-hardened surface layer in service

Ketangguhan Dampak

High — slightly lower than plain Mn13 but well above high chrome iron

Keuntungan

  • Better wear resistance than plain Mn13 in the same duty
  • Higher yield strength, so less deformation in service
  • Retains good toughness for a mixed impact and abrasion duty

Keterbatasan

  • Not suitable where wear is purely low-impact sliding abrasion — high chrome alloy performs better there
  • Requires proper solution treatment to develop its properties

Suku Cadang Keausan yang Cocok

  • Jaw plates for moderate-abrasion feed
  • Secondary and tertiary cone liners
  • Ball mill liners and lifter bars
  • Screen deck and feeder wear plates
  • Bucket teeth and cutting edges

Bagaimana Kami Menggunakan Nilai Ini

Commonly specified where Mn13 wears out too quickly but the application still carries enough impact that a high chrome grade would be at risk of cracking.

Mn18Cr2

Baja Mangan Tinggi Paduan Kromium — Tingkat Keausan Premium

Standar: High-Mn Cr-bearing family · GB/T 5680 ZGMn18Cr2

What Is Mn18Cr2?

Mn18Cr2 combines high manganese content with chromium alloying. It is the grade most often specified for cone mantles, bowl liners and jaw plates in hard abrasive rock, because it delivers the best available balance between work hardening, wear resistance and toughness in one material.

Kimia Khas (% berat)

Karbon (C) 1.10 – 1.45 %
mangan (M N) 17.0 – 19.0 %
Chromium (Cr) 1.80 – 2.50 %
Silikon (Dan) 0.30 – 0.80 %
Fosfor (P) 0.070 % maks

Kekerasan

Khas 210 – 260 HB sesuai ketentuan; lapisan permukaan yang dikeraskan dengan pekerjaan pada umumnya 500 – 600 HB dalam pelayanan

Ketangguhan Dampak

Very high — the most balanced grade for combined impact and abrasion

Keuntungan

  • Best combination of toughness and wear resistance in the manganese family
  • Longer service life than Mn13 or Mn18 in hard abrasive rock
  • Proven in granite, basalt and hard ore applications

Keterbatasan

  • Higher alloy content, so a higher cost per kilogram than standard Mn13
  • Still offers less pure abrasion resistance than high chrome iron in a no-impact duty

Suku Cadang Keausan yang Cocok

  • Mantel kerucut dan pelapis mangkuk
  • Memperbaiki dan mengayunkan pelat rahang
  • Gyratory cekung dan mantel
  • Large impact hammers
  • Mill liners

Aplikasi Khas

Mantel kerucut dan pelapis mangkuk, jaw plates in granite and basalt, gyratory liners, mill liners in abrasive grinding circuits.

Bagaimana Kami Menggunakan Nilai Ini

Widely used as the standard upgrade when a customer needs longer intervals between change-outs in hard rock without accepting the cracking risk of a brittle material.

Besi Paduan Krom Tinggi

Besi Putih Martensit — Cr15, Cr20 dan Cr26

Standar: ASTM A532 Class II / Class III (high-chromium white iron)

What Is High Chrome Alloy Iron?

High chrome alloy iron develops hardness of roughly 58 – 65 HRC through a martensitic matrix carrying hard chromium carbides. It offers the highest abrasion resistance of any wear material we cast, but its toughness is much lower than manganese steel, so it is specified for low-impact, abrasion-dominant duty.

Kimia Khas (% berat)

Karbon (C) 2.00 – 3.30 %
Chromium (Cr) 15.0 – 30.0 % (grade dependent)
Molybdenum (Mo) Up to 1.50 % (where specified)
Nickel (Ni) Up to 2.50 % (where specified)
mangan (M N) 2.00 % maks
Silikon (Dan) 1.00 % maks

Kekerasan

Khas 58 – 65 HRC, with hardness retention generally maintained up to about 350 – 450 °C

Ketangguhan Dampak

Low compared with manganese steel — not suitable for heavy impact or large unbroken tramp metal

Keuntungan

  • Highest abrasion resistance of the grades we cast
  • Hardness retained at elevated temperature, unlike manganese steel
  • Excellent where the material flow is abrasive and impact is limited

Keterbatasan

  • Brittle — will crack or break under heavy impact or tramp metal
  • Not readily weldable in the field
  • Poor choice for primary crushing of large hard rock

Suku Cadang Keausan yang Cocok

  • Impact crusher blow bars
  • Impact plates and breaker plates
  • Hammer heads for limestone and clinker
  • Pulveriser rolls and grinding rings
  • Chute, hopper and bin liners
  • Wear plates and grate bars

Aplikasi Khas

Blow bars, impact plates, hammer heads for limestone and cement, pulveriser rolls and rings, chute and hopper liners, wear plates.

Bagaimana Kami Menggunakan Nilai Ini

Grade is chosen against the feed rather than the crusher model: Cr26 for limestone and clinker where abrasion dominates, Cr20 where some impact is present, and a tougher manganese or alloy steel grade is recommended instead when the feed carries uncontrolled tramp metal.

Baja Karbon & Baja Tuang Paduan Rendah

Pengecoran Struktural dan Komponen Pendukung

Standar: ASTM A27 / A148 · GB/T 11352 (ZG230-450, ZG270-500 families)

What Is Carbon Steel & Baja Tuang Paduan Rendah?

Carbon and low-alloy cast steels are used for structural and support components rather than for the wear surface itself. They provide the toughness, weldability and dimensional stability needed for housings, frames, brackets and bases that carry the wear parts.

Kimia Khas (% berat)

Karbon (C) 0.20 – 0.50 %
Silikon (Dan) 0.20 – 0.60 %
mangan (M N) 0.50 – 1.20 %
Fosfor (P) 0.040 % maks
Sulfur (S) 0.040 % maks

Bagaimana Kami Menggunakan Nilai Ini

Cast, heat treated and machined to drawing, with mounting faces and bolt patterns held to the tolerances required for fitment. Supplied alongside wear parts so that a complete assembly can be sourced from one foundry.

Selection Guide

How to Choose a Material Grade

Material selection follows the failure mode, not the hardness number. These are the decisions we apply when reviewing a wear part application.

01

If: The part fails by cracking or breaking, not by wearing out

Then: Move to a tougher grade — Mn18, Mn22 or a manganese grade in place of high chrome iron. Selecting a harder material makes this failure mode worse, not better.

02

If: The part wears out quickly but the feed delivers strong impact

Then: Stay within the manganese family and raise the grade — Mn13 to Mn18, or Mn13Cr2 to Mn18Cr2. High chrome iron is not suitable where impact energy is high.

03

If: The part wears out quickly in a low-impact, abrasion-dominant duty

Then: Move to high chrome alloy iron (Cr15 to Cr26). Manganese steel cannot work-harden without impact, so its low initial hardness becomes the limiting factor.

04

If: The wear part operates at elevated temperature

Then: High chrome alloy iron retains hardness generally up to about 350 – 450 °C. Manganese steel loses its work-hardening advantage as temperature rises, so grade selection has to follow the operating temperature.

05

If: Wear is uneven across a set of parts, such as a mantle wearing faster than the bowl liner

Then: Check chamber geometry, closed side setting and feed distribution before changing material. Uneven wear is normally a geometry or feed problem rather than a material problem.

06

If: A very large or heavy-section casting relies on work hardening

Then: Confirm the application actually delivers enough impact energy. Very heavy parts in low-impact duty do not work-harden, and a different grade would serve better.
