ASME SA240 ASTM A240 UNS S38100 stainless steel sheetis a hot-rolled or cold-rolled plate from the high-manganese austenitic stainless steel family, engineered with elevated manganese and nitrogen for remarkable resistance to galling, seizing, and wear. Specified under ASME SA240 for pressure vessels and ASTM A240 for general corrosion-resistant applications, this grade—commonly known as XM-15 or Nitronic 33—is solution-annealed for optimal wrought performance. The high Mn (17-19%) content promotes rapid work hardening, while nitrogen enhances strength without compromising ductility, achieving a unique balance of toughness and abrasion resistance.
Unlike conventional 304 or 316 stainless steels that gall under sliding contact, UNS S38100 stainless steel sheets maintain smooth surfaces in high-friction scenarios, offering corrosion resistance comparable to 316 while eliminating the need for costly coatings or lubricants. With a product density of 8.0 g/cm³, these sheets provide an excellent strength-to-weight ratio for fabricating wear plates, chain links, and marine hardware. Gangsteel has exported thousands of tons of ASME SA240 ASTM A240 UNS S38100 stainless steel sheets to clients in Europe, North America, and Asia, backed by ISO 9001 and PED certifications for seamless supply chain integration.

In abrasive and corrosive environments, ASME SA240 ASTM A240 UNS S38100 stainless steel sheets demonstrate superior performance through their unique high-manganese composition. The 17-19% Mn content not only provides galling resistance by promoting austenitic stability under deformation but also enhances pitting resistance through nitrogen synergy, achieving a PREN of approximately 22—comparable to 316 while offering vastly better wear properties. This makes it particularly effective in slurry pumps handling sand-laden seawater or mining screens processing corrosive ores.
Independent testing by ASTM G48 confirms its critical pitting temperature exceeds 25°C in ferric chloride, significantly outperforming 304's 10°C threshold. The alloy's ability to maintain passivity even after mechanical deformation ensures long-term performance in dynamic applications. At Gangsteel, we utilize advanced pickling lines to maximize surface passivation, ensuring your UNS S38100 sheets arrive optimized for immediate deployment. Compare its performance with sa240/a240 uns s32003.

UNS S38100(XM-15 or Nitronic 33) is a high-manganese austenitic stainless steel primarily used for components requiring galling resistance, such as valve stems, pump shafts, and fasteners in mining equipment, food processing machinery, and marine hardware. Its 17-19% Mn content enables rapid work-hardening to 40-50 HRC under sliding contact, eliminating galling without lubricants while maintaining 316-level corrosion resistance in chlorides. Gangsteel supplies ASME/ASTM-compliant sheets for pressure vessels and wear parts, with applications in slurry pumps extending service life 3x over 316. For similar wear grades, see sa240/a240 uns s32900.
UNS S38100provides dramatically better galling resistance than 316 (S31600) due to high Mn (17-19% vs. 2%), achieving work-hardened hardness of 500+ Vickers vs. 316's 200 Vickers, while matching corrosion resistance (PREN ~22 both) in chlorides—ideal for unlubricated sliding where 316 seizes. Yield strength is similar (205 MPa), but S38100 offers 50% higher elongation for forming. 316 suits general corrosion; S38100 wear-critical. Cost: S38100 20% higher but eliminates coatings. Gangsteel recommends for valve upgrades. Equivalents: sa240/a240 uns s32906.
Yes, UNS S38100 welds excellently with GTAW/SMAW using ER381 fillers or ER316L; high Mn reduces hot cracking risk, and no PWHT needed for most thicknesses, though 1050-1100°C anneal optimizes for heavy sections (>12mm). Preheat 100-150°C, interpass <200°C to control dilution. ASTM A262 confirms no sensitization post-weld. Gangsteel provides weld procedures and certificates, supporting multi-pass fabrication with minimal manganese loss for maintained galling resistance. Tips for related grades: sa240/a240 uns s32950.
The density of ASME SA240 ASTM A240 UNS S38100 stainless steel sheet is 8.0 g/cm³ (0.289 lb/in³), identical to standard austenitics despite high Mn, enabling lightweight wear components without density penalties—reduces inertia in dynamic mining equipment by 10%. At Gangsteel, we leverage this for optimized shipping and design calculations.
Pricing for UNS S38100 varies by market and specs, but Gangsteel offers it at approximately $2.10-$2.90 per kg for standard sheets (FOB basis). Thicker plates or custom finishes may increase costs by 10-15%. Contact admin@gangsteel.com for current rates, influenced by manganese surcharges and volume. Bulk orders over 1 ton earn up to 15% discounts. Compare with sa240/a240 uns s32803.
UNS S38100is typically supplied solution-annealed (1050-1120°C, water quench) to maximize corrosion resistance and galling properties; it work-hardens naturally during use rather than through precipitation, but stress relieving at 400-700°C reduces residual stresses after heavy cold working. Avoid 425-900°C sensitization range. Gangsteel performs in-house annealing with certification; consult for custom treatments on sa240/a240 uns s31200.
All UNS S38100 sheets from Gangsteel include EN 10204/3.1 mill test certificates with full chemistry and mechanical testing, PMI reports, and ultrasonic testing results. We also provide third-party inspections (e.g., SGS, BV) and compliance documentation for ASME, ASTM, and PED standards. Our ISO 9001 certification ensures complete traceability from melt to delivery.
