The company’s focus is on precision and high performance-the durability and reliability of the materials supplied are unmatched. Stainless Steel 904L forgings are products offered by the company. Stainless Steel 904L is well known for excellent corrosion resistance in aggressive environments, and this has led to widespread application in chemical processing, marine, oil and gas, and pharmaceutical industries. Chuck Metals ensures high quality craftsmanship with rigorous quality control that delivers bespoke forging solutions tailored to meet the most demanding applications and customer requirements.
Stainless Steel 904L forging is composed of about 23-28% chromium, 4.5-5.5% nickel, 1.5-2.5% molybdenum, 0.2-0.4% copper and small amounts of carbon, silicon, manganese , and phosphorus This alloy provides exceptional corrosion resistance, especially to sulfuric acid, and insoluble with chloride stress. Its mechanical properties include tensile strength of 520-750 MPa, yield strength of 240 MPa and elongation of 40-50%. High nickel content improves ductility, while molybdenum increases resistance to pitting and cracking and corrosion. The hardness of the product remains good even under cryogenic conditions, making it suitable for complex applications.
