Ed Stainless, located in Houston, Texas, is a prominent manufacturer and supplier of high-quality Stainless Steel 439 bars. With its excellent product quality and consistent service, Ed Stainless serves various industrial purposes in different parts of Texas and the USA. Ed Stainless makes its Stainless Steel 439 bars with precision to achieve tough industry standards, providing durability and superior performance for high-temperature applications. Through sophisticated manufacturing techniques and customer-focused operations, Ed Stainless is a reliable partner for companies needing heat-resistant and corrosion-resistant stainless steel solutions across several industries.
Ed Stainless-produced 439 bars have a ferritic stainless steel composition that consists mainly of 17-19% chromium and little to no nickel content. The composition ensures superior corrosion resistance, particularly against stress corrosion cracking and oxidation at elevated temperatures. Mechanically, they are of moderate tensile strength and high ductility, with average values of 450 MPa tensile strength and 20% elongation. The material is ferromagnetic and offers good resistance to chloride environments. Its mechanical strength is well-suited for applications where durability needs to be coupled with resistance to scaling and oxidation.
