Stainless & Corrosion-Resistant Steel — Engineering Reference

Stainless steels are defined by their chromium content (minimum 10.5%), which forms a self-healing passive layer of chromium oxide that resists corrosion. Grades are classified by microstructure: austenitic (300 series), ferritic (400 series), martensitic, and duplex.

Key Standards

ASTM A240/A276/A312, EN 10088, JIS G4304/G4305, GB/T 3280/4237

Common Uses

Food processing equipment, medical implants, chemical tanks, architectural cladding, marine hardware, pharmaceutical piping

Engineer's Note

For welded stainless fabrications, specify the low-carbon variant (304L, 316L) to prevent chromium carbide precipitation at grain boundaries, which causes intergranular corrosion (weld decay).
