CPM-154 CPM S30-V CPM S35-VN CPM S90-V CPM S125-V
We sell five grades of wrought martensitic stainless steel and six CPM stainless grades. They are used in food processing, bearing applications, nozzles, cutlery, valve parts, steam and gas turbine parts and surgical instruments. 416 is the newest grade to our inventory. It is used primarily in the specialty knife industry for bolsters and pins. 418 (Greek Ascoloy) is sold primarily to the gas and steam turbine industry because of it's ability to withstand high stresses at up to 1200F. 420 stainless has the wear resistance of high carbon alloys combined with the corrosion resistance of chromium stainless steels. 440-C and 154-CM are used extensively in the specialty knife business. They are extremely wear resistant due to the high carbon content. Corrosion resistance is increased with the addition of molybdenum and high chromium content.
CPM (Crucible Powder Metallurgy) steels offer superior performance over wrought products. Alloy segregation is minimized and the process produces a very fine microstructure. Cutting applications where edge toughness is required is improved greatly by the CPM process because of the elimination of large carbides. You can also use a much higher alloy content in CPM steels which mproves the toughness and or wear resistance the alloy.
