Kyaw Stainless is a reputable manufacturer and supplier located in Naypyidaw, Myanmar, specializing in top-notch Stainless Steel 310H Nuts. Crafted from high-carbon austenitic stainless steel, these nuts boast remarkable strength, oxidation resistance, and stability even at high temperatures. They’re perfect for high-pressure and high-temperature applications that demand exceptional corrosion resistance and mechanical integrity. At Kyaw Stainless, we prioritize precision engineering, ensuring dimensional accuracy and compliance with international standards for durable and reliable fastening solutions. Our 310H Nuts are extensively utilized in industries that require resilience and performance in extreme thermal and corrosive conditions.
Stainless Steel 310H Nuts are composed of chromium (24–26%), nickel (19–22%), and a carbon content of up to 0.10%, which enhances their tensile strength and creep resistance. This alloy excels in resisting oxidation and carburization at temperatures up to 1100°C. With a tensile strength of around 515 MPa, yield strength of 205 MPa, and an elongation of 40%, these nuts provide toughness and stability under heat and stress. Their hardness, approximately 80 HRB, combined with high carbon content, reinforces their structural integrity, making them ideal for challenging high-temperature and corrosive industrial settings.
