304 Stainless Steel Coils Definition

Grade 304 Stainless Steelis the standard "18/8" stainless; it is the most versatile and most widely used stainless steel, available in a wider range of products, forms and finishes than any other. It has excellent forming and welding characteristics. The balanced austenitic structure of Grade 304 enables it to be severely deep drawn without intermediate annealing, which has made this grade dominant in the manufacture of drawn stainless parts such as sinks, hollow-ware and saucepans. For these applications it is common to use special "304DDQ" (Deep Drawing Quality) variants. Grade 304is readily brake or roll formed into a variety of components for applications in the industrial, architectural, and transportation fields. Grade 304 also has outstanding welding characteristics. Post-weld annealing is not required when welding thin sections.

Possible alternative grades to 304 grade stainless steel

Grade

Why it might be chosen instead of 304

301L

A higher work hardening rate grade is required for certain roll formed or stretch formed components.

302HQ

Lower work hardening rate is needed for cold forging of screws, bolts and rivets.

303

Higher machinability needed, and the lower corrosion resistance, formability and weldability are acceptable.

316

Higher resistance to pitting and crevice corrosion is required, in chloride environments

321

Better resistance to temperatures of around 600-900°C is needed…321 has higher hot strength.

3CR12

A lower cost is required, and the reduced corrosion resistance and resulting discolouration are acceptable.

430

A lower cost is required, and the reduced corrosion resistance and fabrication characteristics are acceptable.
