At Mitchell Stainless in Hamilton, New Zealand, we supply high-quality stainless steel fasteners designed for strength, durability, and reliability. Our Stainless Steel 301 Nuts are made from austenitic stainless steel, offering excellent corrosion resistance and good mechanical performance. Ideal for structural, industrial, and light engineering applications, these nuts provide secure fastening even in harsh or mildly corrosive environments. Supported by Mitchell Stainless’ commitment to quality and local expertise, 301 nuts are a trusted choice for customers seeking long-lasting, dependable fasteners that combine strength, corrosion resistance, and ease of use in a variety of applications.
Stainless Steel 301 Nuts are manufactured from an austenitic stainless steel alloy containing chromium and nickel. This composition ensures good tensile strength, toughness, and corrosion resistance in indoor and outdoor environments. The nuts retain dimensional stability and mechanical performance under standard load conditions and provide excellent resistance to oxidation and wear. Stainless Steel 301 maintains non-magnetic properties in the annealed condition and offers good work-hardening characteristics, making it suitable for fastening applications where reliability, durability, and corrosion resistance are essential.
