Harsh Metalloys is a leading manufacturer and exporter of Stainless Steel 436 Nuts, located in Mumbai, India. The company is well known for its quality standards and technical know-how and provides precision-engineered fasteners that are strictly in accordance with national and international standards. With a keen focus on quality check, Harsh Metalloys provides Stainless Steel 436 Nuts that guarantee durability, resistance to corrosion, and high performance in harsh environments. Their timely delivery, competitive prices, and customer-oriented attitude have created a strong reputation in industries like automotive, construction, and engineering and made them one of the most reliable names in India’s fastener industry.
Harsh Metalloys’ Stainless Steel 436 Nuts in Mumbai, India, are made up of mostly iron with 16–18% chromium and 0.75–1.25% molybdenum for improved corrosion and oxidation resistance. The low carbon content decreases the precipitation of carbides, enhancing weldability and toughness. Mechanically, the nuts exhibit a tensile strength of approximately 520 MPa and yield strength of about 310 MPa. They possess good ductility, formability, and scaling resistance at elevated temperatures. Such mechanical and chemical properties ensure Harsh Metalloys’ SS 436 Nuts are a consistent bet for uses that necessitate structural strength and environmental degradation resistance.
