Nakamura Stainless, located in Pulau Ujong, Singapore, is a well-known manufacturer and supplier of high-quality stainless steel products, including stainless steel 405 bars. These bars are recognized for their excellent heat resistance and moderate corrosion resistance. They are widely used in situations that require good strength and oxidation resistance at high temperatures. Nakamura Stainless practices precise manufacturing and strict quality control, producing durable and reliable bars suitable for various industries, including automotive, furnace components, and heat treatment equipment.
Stainless steel 405 bars are a ferritic stainless steel alloy made mostly of about 11.5 to 12.5% chromium and have very low carbon content. This combination provides good resistance to oxidation and scaling at temperatures up to 900°C. The alloy has moderate mechanical strength, with tensile strength usually around 450 to 600 megapascals. Its ferritic structure offers good resistance to stress corrosion cracking and better thermal conductivity compared to austenitic grades. Stainless steel 405 bars are also magnetic and allow for good weldability when proper precautions are taken.
