Stainless Steel Screws & Fasteners
Stainless steel screws, bolts, and fasteners in A2 and A4 grades — corrosion-resistant solutions for demanding environments.
Stainless Steel Material & Standard Comparison
| Material | Properties | Common Standards | Typical Applications |
|---|---|---|---|
| 304 (A2) | Good corrosion resistance, cost-effective | DIN 933/934, ISO 4017, GB/T 5783 | Construction, furniture, general industry |
| 316 (A4) | Resistance to chloride ion corrosion, suitable for marine/chemical environments | DIN 931/933, ISO 4014, ASTM A193 B8M | Marine, chemical, food processing equipment |
| 410 (Martensitic) | High hardness, wear-resistant, heat-treatable | GB/T 3098.6, DIN 267 | Pumps and valves, shafts, cutting tools |
| 201 | Economical grade, lower corrosion resistance than 304 | GB/T 3098.6, JIS G4305 | Indoor decoration, low-requirement structures |
*Custom non-standard materials and special surface treatments (Dacromet, PTFE, zinc plating, etc.) are available based on drawings or samples.
