Corrosion Resistant Stainless Steel Fasteners
Corrosion resistant stainless steel fasteners from Zhejiang Chance & Union Import and Export Co., Ltd. are manufactured from austenitic, duplex, and precipitation-hardening stainless steel grades. These fasteners are designed for service in moisture, chemical, and high-temperature environments where carbon steel or coated fasteners would fail. The product line includes bolts, nuts, washers, pins, screws, and non-standard custom parts. Supported by a 33,350 m² facility and an annual production capacity of 9,500 tons, we supply global buyers with stable, traceable, and specification-matched fastening components.
Core Advantages
Material and Grade Selection
We process 304, 316, 316L, 321, 904L, duplex 2205, 2507, and other corrosion resistant stainless steel grades. Material certificates and grade verification are provided before production.
Production Capacity
The factory operates automated cold heading, hot forging, and CNC machining lines. Annual capacity reaches 9,500 tons, supporting both OEM bulk orders and ODM development projects.
Quality System
ISO9001 and IATF16949 certified processes with full digital traceability. Each batch maintains quality records and a long-term tracking mechanism for after-sales analysis.
Customization Support
Non-standard dimensions, special heads, grooves, and ultra-long or thin parts are produced according to customer drawings, parameters, and application conditions.
Supply Chain Coordination
Raw material procurement and production cycles are managed under one supply chain structure, reducing lead time fluctuations for repeated orders.
Service Response
A multi-to-one service team operates 340 days per year with pre-sales and after-sales response times under 12 hours. Factory technical response is within 30 minutes.
