Welcome to our Houston-based company, where we take pride in being a reliable manufacturer and supplier of top-notch stainless steel sheets, plates, and structural components, including our Stainless Steel 348H Channels. Designed to excel in high-temperature and corrosive settings, these channels are perfect for industrial applications that deal with intense heat and pressure. We ensure that our products comply with ASTM and international standards, guaranteeing dependable mechanical strength and outstanding weldability. With a commitment to quality, precision, and timely delivery, we cater to industries like chemical processing, power generation, and aerospace engineering.
When it comes to composition and mechanical properties, Stainless Steel 348H is a niobium-stabilized austenitic stainless steel that contains 17–20% chromium, 9–13% nickel, and a higher carbon content (up to 0.10%) to boost its high-temperature strength. The addition of niobium enhances resistance to intergranular corrosion and helps stabilize the material during welding and thermal exposure. This alloy boasts a tensile strength of about 515 MPa and a yield strength of around 205 MPa. It also maintains excellent creep and stress rupture resistance at elevated temperatures, along with good weldability, making it a great choice for high-heat structural and pressure applications.
