Frequently Asked Questions:
What is 310 stainless steel used for?
SS 310 is used in extremely high-temperature applications such as furnace parts, heat treatment equipment, radiant tubes, kilns, incinerators, burner nozzles, and chemical processing equipment. It performs reliably up to 1150°C, making it a go-to grade for the cement, petrochemical, power generation, and steel industries wherever heat and oxidation resistance are the priority.
Which is better, 310 or 316 stainless steel?
These two grades serve completely different purposes. SS 316 is better for corrosion resistance, especially in marine, chloride-rich, and chemical environments. SS 310 is better for high-temperature resistance; it handles heat up to 1150°C, where 316 would fail. If your application involves saltwater or acids, choose 316. If it involves furnaces or high heat, choose 310.
Is 310 stainless steel good?
Yes, for the right application, SS 310 is excellent. It has outstanding oxidation resistance, good mechanical strength at elevated temperatures, and performs well in both oxidising and reducing atmospheres. However, it is not ideal for welded structures in corrosive environments or for applications where cost is the primary concern. Used correctly, it is one of the most reliable high-temperature alloys available.
Can SS 310 be welded?
Yes. SS 310 can be welded using SS 310 filler wire. Preheating is not required. Post-weld annealing is recommended for optimal corrosion resistance.
What is the price of SS 310 per kg in India?
SS 310 price in India ranges between ₹ 320 – ₹ 420 per kg, depending on product form, thickness, and quantity. Contact us for confirmed pricing with MTR.
What is the difference between 310 and 310S stainless steel?
The main difference is carbon content. Grade 310 has a higher carbon maximum (0.25%), which gives it slightly better high-temperature strength but can lead to carbide precipitation in welded joints. Grade 310S has a lower carbon maximum (0.08%), which reduces this risk, making 310S the preferred choice for welded applications and components requiring post-weld heat treatment.
What is the temperature limit of SS 310?
SS 310 can withstand continuous service up to 1100°C (2012°F) and intermittent service up to 1150°C (2102°F) in oxidising atmospheres. In sulphur-containing environments, the continuous service limit is lower. Always verify operating conditions against ASME Section II Part D allowable stress tables.
What is the UNS number for 310 stainless steel?
The UNS number for Grade 310 is S31000 and for Grade 310S is S31008. The DIN Werkstoff numbers are 1.4841 (310) and 1.4845 (310S).
