Stainless Steel Heat Treatment Services

Three methods to restore stainless steel properties

Solution Annealing:

1010-1120℃ quenching for intergranular corrosion resistance
Your Gain: Passes ASTM A262 test for chemical tanks

Stress Relieving:

400-600℃ slow cooling, keeps hardness
Your Gain: <0.1mm/m distortion for precision parts

Quenching:

Oil quench+temper for martensitic steels (e.g. 420)
Your Gain: Cutlery hardness up to HRC55

Quality Assurance

Atmosphere-controlled furnaces
Heat treatment graphs & hardness reports
