SUS 440C equal material :UNS 44004 ,X105CrMo17,material 1.4125
SUS 440C comprehensive description
SUS 440C stainless steel with long lasting protection of corrosion resistance is the surface substrate material. It requires no additional system, in order to protect the base metal, the metal itself will continue. Stainless steel products to complete its service life. Due to the raw material is 100% recyclable, have focused on processing. In fact, more than 50% of new stainless steel stainless steel scrap from down, thus completed the full life cycle is used again. So, in the project life cycle is stainless steel, is often the most valuable choice.

SUS 440C heat treatment process
1) annealing, 800 -920 degree slow cooling.
2) quenching, 1010 - 1070 degree oil cooling;
3) tempering, 100 -180 degree cold fast.
SUS 440C scope of application:
Mainly used in the manufacture of the corrosion environment and no lubrication bearing working parts in strong oxidizing atmosphere.SUS 440C has good temperature resistance; high temperature size so can also be used as corrosion resistant high temperature bearing steel. In addition, can also be used to manufacture high quality tools, such as medical scalpel,scissors, nozzle, bearings, etc. SUS 440C , is to improve the performance of SUS 440Csteel free cutting steel, used for automatic lathe, as well as ordinary alloy steel by quenching hardening characteristics, thus can be obtained by selecting the brand and heat treatment conditions to wide range of different mechanical properties.SUS 440C under dynamic load capacity is low.Stainless steel SUS 440C can be produced as SUS 440C stainless steel plates, SUS 440C stainless steel bar,SUS 440C stainless steel wire, SUS 440C stainless steel forging product.
