ASTM A564 Type 630 H1100 Stainless Steel bar
Leave a message
What is A564 type 630 material?
ASTM A564 is a standard material specification for hot-rolled and cold-finished age-hardening stainless steel bars, including type 630 / UNS S17400 / 17-4 PH used for parts requiring corrosion resistance and high strength at room temperature, or at temperatures up to 600°F [315°C].
What is H1100 material?
Stainless Steel 17-4 H1100 is a precipitation-hardening martensitic Stainless Steel, which has corrosion resistance comparable to austenitic varieties. Our H1100 has been heat-treated to a minimum tensile strength of 140ksi, yield strength of 115ksi, an elongation in 2in of 14%, and a reduction of area of 45%.
What is the difference between H900 and H1100?
The H900 condition using solution annealing, rapid quenching, and aging generates a predominantly martensitic microstructure that maximizes strength and hardness. H1100 treatment creates some ferrite fraction by slightly slower cooling, enhancing toughness.
