Which Stainless Grade to Use<\/h2>\n

Grade 304 is the general purpose choice. It resists food processing, fresh water and most architectural environments.<\/p>\n

Grade 316 adds molybdenum for chloride resistance, so it is the standard for coastal sites, marine hardware and chemical plant.<\/p>\n

Grade 316L is the low-carbon variant, used where parts are welded and where intergranular corrosion would otherwise be a risk.<\/p>\n

Strength Compared with Carbon Steel<\/h2>\n

Austenitic stainless is ductile rather than extremely strong. A2-70 stainless bolts reach roughly 700 MPa tensile strength, which is below class 10.9 carbon steel.<\/p>\n

Where a stainless bolt replaces a high grade carbon bolt, check the joint design rather than assuming the same preload is available.<\/p>\n

Preventing Galling<\/h2>\n

Stainless threads can seize when tightened dry, a failure called galling. The surface tears and the nut welds itself to the bolt.<\/p>\n

Use an anti-seize lubricant, choose a nut in a different grade, or specify a coated stainless thread. Slower tightening also helps.<\/p>\n

Matching Bolts, Nuts and Washers<\/h2>\n

Use the same grade family for bolt, nut and washer so the assembly corrodes evenly.<\/p>\n

Avoid pairing stainless with galvanized components in a wet environment, because the galvanized part becomes the sacrificial anode and corrodes quickly.<\/p>\n
