440A 440B 440C Stainless H Beam

 

 

440A, 440B, 440C are high-chromium martensitic stainless steel, in the quenched and tempered state, have high strength, high NMness, and both stainless steel, corrosion resistance. Three kinds of stainless steel organizational structure for the body-centered cubic structure, and thus at high temperatures the strength will drop sharply. Below 600 ℃, high temperature strength is the highest in all types of stainless steel, creep strength is also the highest.

 

Comprehensive performance comparison
Carbon content: 440C＞440B＞440A
Hardness after quenching: 440C＞440B＞440A
Wear resistance after quenching: 440C > 440B > 440A
Toughness after quenching: 440A＞440B＞440C

 

440A, 440B, 440C these three ss carbon content is slightly higher, after appropriate heat treatment can obtain a high yield strength, NMness can reach 58HRC, and thus in the NMened state of NM, high toughness, belongs to the NMest stainless steel. Mainly used for high strength, abrasion resistance, corrosion resistance requirements of high edged tools, gauges, bearings and other parts manufacturing.
