Standard and Manufacturing Overview

1. SMLS (Seamless Manufacture)
   • Produced via hot piercing or cold drawing, eliminating weld seams for uniform integrity in high-pressure/high-temperature systems.
2. Material Grades (Austenitic Stainless Steel)
   • TP304/304L: 18Cr-8Ni (304) and low-carbon (304L, C ≤ 0.03%) variants.
   • TP316/316L: 16Cr-10Ni-2Mo (316) and low-carbon (316L) grades, with Mo enhancing chloride resistance.

 

Technical Specifications and Applications

Grade	Chemical Composition (Key Elements)	Mechanical Properties (Min.)	Corrosion/Heat Resistance
TP304	Cr 18-20%, Ni 8-10.5%, C ≤ 0.08%	Tensile strength: 515 MPa Elongation: 30%	Good general corrosion resistance; suitable for non-aggressive acids and food-grade environments
TP304L	Cr 18-20%, Ni 8-12%, C ≤ 0.03%	Tensile strength: 485 MPa Elongation: 35%	Low-carbon avoids carbide precipitation (weld decay resistance); ideal for welded components in chemical processing
TP316	Cr 16-18%, Ni 10-14%, Mo 2-3%, C ≤ 0.08%	Tensile strength: 515 MPa Elongation: 30%	Mo improves resistance to pitting/crevice corrosion in chloride solutions (e.g., seawater, brine)
TP316L	Cr 16-18%, Ni 10-14%, Mo 2-3%, C ≤ 0.03%	Tensile strength: 485 MPa Elongation: 35%	Low-carbon variant for welded parts in marine, pharmaceutical, and saltwater applications

• TP304/304L:
  • Food & Beverage: Brewing tanks, dairy processing lines (CIP/SIP compatible).
  • Chemical Processing: Non-chlorinated acid transport (e.g., acetic acid), general-purpose piping.
  • Architectural: Decorative railings, outdoor structures (304L for coastal areas).
• TP316/316L:
  • Marine & Offshore: Seawater cooling systems, shipboard piping (Mo resists chloride pitting).
  • Pharmaceuticals: Reactor vessels, sterile process lines (316L for weldability in GMP environments).
  • Oil & Gas: Downhole tubing in mildly corrosive wells, offshore platform pipelines.
