Made from SS316 stainless steel (equivalent to A4, 1.4401), this bolt contains molybdenum (Mo) to resist pitting, crevice corrosion, and chemical erosion—outperforming SS304 in marine, chemical, and food-processing settings. Available in grades A4-70 and A4-80, it balances high tensile strength (minimum 520 N/mm²) with excellent ductility, making it suitable for both structural and precision applications. We offer sizes from M3 to M100 (with non-standard options via OEM) and provide EN10204-3.1B certification to ensure traceability and quality.
SS316 stainless steel (1.4401) contains 16.0-18.0% chromium (Cr), 10.0-14.0% nickel (Ni), and 2.0-3.0% molybdenum (Mo), forming a dense oxide layer that withstands saltwater, acids, and industrial chemicals.
Ideal for outdoor, marine, or chemical plant use, where SS304 bolts may fail due to corrosion.
Complies with multiple international standards: DIN931 (partially threaded), DIN933 (fully threaded), ISO4014/4017, ASME B18.2.1, and JIS B1180, ensuring compatibility with global projects.
Size range: M3 to M100; non-standard lengths, thread pitches, or head designs are available via custom orders (based on drawings or samples).
Grade A4-70: Minimum tensile strength (Rm) of 520 N/mm², yield strength (RP0.2) of 205 N/mm², and elongation (A5) of 40%, suitable for general load-bearing.
Grade A4-80: Higher strength for heavy-duty use, with enhanced durability in high-pressure environments.
Default marking: “HT&FST”; custom markings (e.g., grade, brand) are available to meet project specifications.
EN10204-3.1B certified, providing detailed material analysis and performance test reports for each batch.
Marine & Offshore Industry: Secures ship hulls, offshore platforms, and coastal infrastructure. SS316’s 2–3% molybdenum content resists saltwater corrosion and humid, salt-laden air—outperforming SS304 in harsh marine environments.
Chemical & Pharmaceutical Equipment: Fastens reactors, storage tanks, and mixing machines in chemical plants/pharmaceutical facilities. Withstands acids, alkalis, and sterile cleaning agents, maintaining hygiene and structural integrity.
Food & Beverage Processing: Used in brewing equipment, dairy machinery, and conveyor systems. Its “Bright&Clean” finish prevents bacterial buildup, complying with food safety regulations (FDA, EU 10/2011).
Precision Engineering: Suitable for medical devices, semiconductor equipment, and aerospace components (Grade A4-80). Balances high tensile strength (520 N/mm² min) and ductility, ensuring reliability in precision applications.
