FAQ: Common Questions About ASME SA240 ASTM A240 UNS S32615 Stainless Steel Sheet

What is UNS S32615 stainless steel used for?

UNS S32615is a high-silicon austenitic stainless steel primarily used in corrosive environments like hot concentrated sulfuric acid processing, desalination, and offshore oil platforms. Its elevated silicon provides superior oxidation resistance. At Gangsteel, we supply it for applications such as heat exchangers, pressure vessels, and piping, ensuring compliance with ASME SA240 and ASTM A240 standards. For similar uses, consider our sa240/a240 uns s32003.

What are the differences between UNS S32615 and 316L stainless steel?

While both are austenitic, UNS S32615 offers enhanced oxidation resistance due to high silicon (4.8-6% vs. <1% in 316L) and higher Ni (19-22% vs. 10-14%), making it suitable for hot acids. 316L has better general corrosion but lower high-temp performance; S32615 yield ~250 MPa vs. 170 MPa. Gangsteel recommends S32615 for sulfuric acid upgrades. See equivalents in our sa240/a240 uns s32101 lineup.

Is UNS S32615 stainless steel weldable?

Yes, UNS S32615 is weldable using GTAW (TIG) or SMAW with matching fillers like ERNiCr-3. Low carbon prevents sensitization; post-weld annealing recommended for full properties. Avoid overheating. Gangsteel provides weld test certificates with every order. For welding guides on related grades, visit our sa240/a240 uns s32900 page.

What is the density of UNS S32615 stainless steel?

The density of ASME SA240 ASTM A240 UNS S32615 stainless steel sheet is 7.6 g/cm³ (0.275 lb/in³), slightly lower than standard austenitics due to high Si. This makes it ideal for weight-sensitive designs without compromising strength. At Gangsteel, we factor this into shipping quotes for efficiency.

How much does UNS S32615 stainless steel cost per kg?

Pricing varies by market and specs, but Gangsteel offers UNS S32615 at approximately $2.50-$3.50 per kg for standard sheets (FOB basis). Thicker plates or custom finishes may increase costs. Contact admin@gangsteel.com for current rates, influenced by alloy surcharges and volume. Compare with sa240/a240 uns s32906.

Can UNS S32615 be heat treated?

UNS S32615is typically supplied solution-annealed (1050-1150°C, water quenched) for optimal corrosion resistance. It doesn't harden via precipitation but can be stress-relieved at 400-700°C. Gangsteel performs in-house annealing; consult us for custom treatments on sa240/a240 uns s32950.

What certifications are available for Gangsteel UNS S32615 sheets?

All UNS S32615 sheets from Gangsteel come with EN 10204/3.1 mill test certificates, PMI reports, and ultrasonic testing.
