347 stainless steel plate which strength is increased
Grade 316 is available in virtually all stainless product forms including coil, sheet, plate, strip, tube, pipe, fittings, bars, angles, wire, fasteners and castings. 316L is also widely available, particularly in heavier products such as plate, pipe and bar. Most stainless steel surface finishes, from standard to special finishes, are available. 347 Bar 347 Stainless Steel 347 Round Bar Supplier In strongly oxidizing environments 347 offers slightly better resistance to corrosion to 321. Depending on the form, plate, sheet or bar, the grain size and amount of carbon could possibly meet the 347H and 347S requirements. 347 stainless steel can be used in oil and gas, heater tubes, reactor equipment and many other applications.
347 stainless is an austenitic stainless steel offering an excellent resistance to inter-granular corrosion following exposure to temperatures in the chromium carbide precipitation range from 800 to 1500O F. Alloy 347 alloyed with columbium-tantalum (referred to as niobium) allows good mechanical properties at high temperatures. 347 Stainless Steel Plate, Sheet, and Round BarThe 347 stainless steel grade is a stabilized alloy, due to its columbium + tantalum component within. Ideal for long-term work life in high temperatures (800-1500ºF), 347 Stainless Steel is also resistant to intergranular corrosion in the chromium carbide precipitation range. High creep and stress rupture properties are part of their superior mechanical properties. 347H Stainless Steel Sheet, ASTM A240 Grade 347H Stainless Alloy 347H is the higher carbon (0.04 0.10) version of the alloy. It was developed for enhanced creep resistance and for higher strength at temperatures above 1000oF (537°C). In most instances, the carbon content of the plate enables dual certification. Alloy 321 cannot be hardened by heat treatment, only by cold working.
Alloy 347H (UNS S3409) stainless steel plate is the higher carbon (0.04 0.10) version of the alloy. It was developed for enhanced creep resistance and for higher strength at temperatures above 1000°F (537°C). In most instances, the carbon content of the plate enables dual certification. ATI 302/ATI 304/ATI 304L/ATI 305Minimum mechanical properties for annealed ATI 302, ATI 304, ATI 304L and ATI 305 austenitic stainless steel plate, sheet and strip as required by ASTM specifications A 240 and ASME specification SA-240 are shown below.
