Steels - (High Chromium Steels) Stainless Steels

High carbon high chrome steels are heat treatable as a consequence of the higher carbon content, and are known as martensitic stainless steels (e.g. 410, 416). They do, however, exhibit lower corrosion resistance due to chromium depletion of the oxide film.

Ni-Hard - Nickel Institute

Ni-Hard Ni-Hard is the generic name for a family of white cast irons alloyed with nickel and chromium to give high hardness and outstanding resistance to abrasion. There are two distinct groups of Ni-Hard compositions: • the medium alloyed Ni-Hard 1 and Ni-Hard 2 with, nominally, 3.3% (resp 2.6%) C, 4% Ni, 2% Cr • Ni-Hard 4 with,

White Iron Foundry - Townley Engineering & With five induction furnaces capable of pouring up to 16 tons of white iron, we consistently have some of the shortest lead times in the industry. Townley Foundry produces many alloys on a regular basis like High chrome HC-27, HC28, NIHARD4 and CM-22 (chrome-moly) for abrasion resistance and HC-34, CD-4 MCU, GR4 and other alloys for better corrosion resistance.annealing and re-hardening ASTM A532-93 Class RE: annealing and re-hardening ASTM A532-93 Class III Type A high chrome abrasion resistant cast iron arunmrao (Materials) 11 Oct 16 18:38 As a first step, I would temper this casting to drop the hardness to BHN, before attempting annealing.

(PDF) Microstructural Modifications of AsCast The initial as-cast microstructure of a high-chromium (2.35% C, 18.23% Cr) white cast iron consisting of primary austenitic dendrites and a eutectic mixture of M7C3 carbides/austenite was extensively modified by four different heat treatments: H.T.A:

CNA - High-chrome wear-resistant The invention discloses a high-chrome wear-resistant cast iron material and a heat treatment method. The high-chrome wear-resistant cast iron material is prepared from iron as a main raw material, and carbon, silicon, manganese, sulphur, phosphorus, chrome, molybdenum, nickel and copper as auxiliary materials in manners of melting and casting after preparation.
