FAQ: Common Questions About ASME SA240 ASTM A240 UNS S34565 Stainless Steel Sheet

 

What is UNS S34565 stainless steel used for?

UNS S34565is a super austenitic stainless steel for severe corrosion like chemical reactors handling hot acids, offshore subsea equipment in seawater, and desalination brine lines. High Mo (4-5%) and N (0.4-0.6%) deliver PREN >45 for pitting/crevice resistance, outperforming 904L in chlorides up to 100°C. Gangsteel offers ASME/ASTM sheets for pressure vessels/piping, with applications in urea synthesis reducing failures 30%. Alternatives: sa240/a240 uns s32803.

What are the differences between UNS S34565 and 904L stainless steel?

UNS S34565trumps 904L (N08904) with higher N (0.4-0.6% vs. 0.1%) for 50% more yield (310 MPa vs. 220 MPa), plus balanced Mo (4-5% vs. 4%) for better weldability and PREN 45 vs. 36 in hot chlorides. 904L suits mild acids; S34565 extreme seawater/acids. Cost: S34565 20% pricier but halves maintenance. Gangsteel suggests for offshore. Equiv: sa240/a240 uns s31200.

Is UNS S34565 stainless steel weldable?

Yes, UNS S34565 welds superbly with GTAW/SMAW and ERNiCrMo-3 fillers; low C (≤0.02%) and high N resist hot cracking, no PWHT typically needed but optional 1100°C anneal for max corrosion. Interpass <150°C, preheat 100°C for thick. Tests confirm no sigma phase post-cycle. Gangsteel certs welds for vessel code. Guides: sa240/a240 uns s31260.

What is the density of UNS S34565 stainless steel?

ASME SA240 ASTM A240 UNS S34565 stainless steel sheetdensity: 8.0 g/cm³ (0.289 lb/in³), standard for super austenitics, enabling compact designs in weight-critical offshore/desal apps without ductility loss. Supports 15% material savings. Gangsteel fine-tunes shipping.

How much does UNS S34565 stainless steel cost per kg?

Gangsteel: ~$2.90-$3.95/kg standard (FOB), per Mo/N; thick/custom +12%. 1+ ton: 15% rebate. Fluctuates; admin@gangsteel.com current. Vs. 904L: 15% more for superior strength. Cf. sa240/a240 uns s32001.

Can UNS S34565 be heat treated?

UNS S34565solution anneals 1120-1170°C (quench) to optimize passivity; N stabilizes, no hardening, stress-relieve 400-600°C if formed. Shun 600-900°C to dodge sigma. Gangsteel treats onsite, micro-verified for 100°C chlorides. Cycles: sa240/a240 uns s32003.

What certifications are available for Gangsteel UNS S34565 sheets?

Gangsteel's UNS S34565 sheets boast EN 10204/3.1 MTCs (chem/mech/heat), PMI/UT, third-party (SGS/BV) for compliance/ASME/ASTM/PED. ISO 9001 traceability; NACE MR0175 optional for sour. Enables code stamping. Details: sa240/a240 uns s32101.
