Midland, UK-headquartered Westeon Stainless is a reputed provider of top-quality stainless steel products offering precision-engineered parts for industrial sectors. Some of their offerings are the extensively utilized Stainless Steel 304H Pipes that owe their popularity due to excellent high-temperature properties, corrosion, and toughness. The pipes are produced using Grade 304H stainless steel having more carbon, thereby making mechanical properties superior. Seamless, welded, ERW, and fabricated forms are available for them, catering to a variety of industrial requirements. 304H material content makes them deliver great performance, thus they find extensive application in heat exchangers, boilers, power generation plants, chemical processing, and structural uses at elevated temperatures.
Stainless Steel 304H Pipes consist of carbon (0.04-0.10%), chromium (18-20%), nickel (8-11%), manganese (≤2%), silicon (≤1%), phosphorus (≤0.045%), and sulfur (≤0.03%), offering superior high-temperature strength and corrosion resistance. Their mechanical properties are tensile strength of ≥515 MPa, yield strength of ≥205 MPa, elongation of ≥40%, and hardness of ≤201 Brinell (HB). The physical characteristics encompass a density of 8.0 g/cm³, a melting point in the range 1400-1450°C, thermal conductance of 16.2 W/m·K, and electrical resistivity of 720 nΩ·m, for applications under high pressure and temperatures.
