White Industries are one of Australias most advanced foundry businesses producing highly specialised castings in Queensland for a range of companies around the world.
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.
2020-4-21With stress-relieving heat treatment the tension in the material is minimised without changes to the chrome and vanadium. They offer high resistance to adhesive and abrasive wear with high toughness as well as high resistance to pressure and high temperatures. effects of the Iron Sulphide.
Heat treatment is the process of heating and cooling metals to change their microstructure and to bring out the physical and mechanical characteristics that make metals more desirable.
2020-6-15Iron processing - Iron processing - The metal Most blast furnaces are linked to a basic oxygen steel plant for which the hot metal typically contains 4 to 4.5 percent carbon 0.6 to 0.8 percent silicon 0.03 percent sulfur 0.7 to 0.8 percent manganese and 0.15 percent phosphorus.
Ductile cast iron was invented in the early to mid-1940s. 4 Malleable Cast Iron. Finally malleable cast iron that easily workable. Its typically created using heat treatment processes on white cast iron.
However iron carbide or cementite is extremely hard and brittle and these castings are used where high hardness and wear resistance is needed. Malleable irons.

2020-6-13The quality and profitability of iron castings are driven by the metallurgy of the melt the design of the pattern the productivity of the process reproducible manufacturing conditions and the resulting properties of the cast iron material after casting and heat treatment.
Machining of hard-to-wear materials such as high-chrome white cast iron HCWCI and high-manganese steels is an uphill task when conventional route followed. Alternatively thermally enhanced machining TEM can be used to minimie the tooling cost very effectively.
1. Cast iron with 2.9 C and 13.6 Cr has the highest and cast iron with 2.8 C and 29 Cr the lowest thermal conductivity and the highest modulus of elasticity and electrical resistivity of the alloys investigated. 2. In contrast to steels the transformation temperature A1 is higher than the Curie temperature A2 for the cast irons investigated. 3.

A popular grade of white iron is high chrome white irons ASTM A532. This contains nickel and chromium for good low-impact abrasion applications 4. Malleable cast iron.
H.T.W. is a high chromium white cast iron that is used where high corrosion and abrasion resistance are required. It also has excellent growth and scaling resistance under oxidising conditions. A modified H.T.W.
RE high chromium white cast iron nucleation EdStainless Materials 29 Sep 14 1301 I understand what you are saying about gray irons if they are held in the furnace too long you loose inoculation and you need to freshen the heat so that you get good graphite formation.
