Hastelloy B2 nuts (commonly referred to as ‌B2 alloy nuts‌) are designated under international standards as:

  • UNS N10665‌ (Unified Numbering System)
  • NiMo28‌ (DIN/Werkstoff Germany)
  • NS322‌ (GB/T China) ‌12.

Super Duplex 2507 (UNS S32750, EN 1.4410, SAF 2507) is a high-performance ‌super duplex stainless steel‌ combining austenite and ferrite phases in a 50:50 ratio. Its exceptional performance stems from a precise chemical composition and advanced micro structure

‌duplex 2205 (UNS S32205/S31803, EN 1.4462) is a dual-phase stainless steel combining austenite and ferrite microstructures in a balanced ratio.

316 stainless steel nuts are critical components in industries requiring exceptional corrosion resistance and durability.

316L stainless steel is recognized under multiple international standards, ensuring global compatibility:

  • AISI/SAE‌: 316L
  • UNS‌: S31603 ‌14
  • ISO‌: X2CrNiMo18-14-3
  • DIN‌: 1.4404 ‌58
  • JIS‌: SUS 316L ‌34
