Frequently Asked Questions (FAQs)

1. How strong is stainless steel bar?

It has good ductility in the annealed condition but is capable of being hardened up to Rockwell Hardness 50HRC, the highest hardness of the 12 per cent chromium grades. Its best corrosion resistance is achieved when the metal is hardened and surface ground or polished.

2. What are stainless steel round bars used for?

Some common applications of steel round bar include frameworks, supports, braces, shafts, and axles. Stainless steel round bars are highly corrosion resistant. The stainless steel will tolerate high levels of acidity and can be used in chlorine bearing environments or alkaline solutions.

3. Which is better SS 304 or 316?

Though the stainless steel 304 alloy has a higher melting point, grade 316 has a better resistance to chemicals and chlorides (like salt) than grade 304 stainless steel. When it comes to applications with chlorinated solutions or exposure to salt, grade 316 stainless steel is considered superior.
