15X5M - 1.7362 - aisi 501 pipe

15X5M - 1.7362 - aisi 501 pipe


Grade 15X5M is a high-alloy heat-resistant steel used for parts operating in an unloaded state at high temperatures 900−1000°C. Belongs to the group of austenitic-ferritic alloys. In comparison with austenitic — steel 15H5M has higher reliability and resistance to intergranular corrosion and greater resistance to stress corrosion cracking in alkaline and chloride environments.

The composition and advantages

Stainless steel pipe of steel grade 15H5M (according to GOST 5632−72) in its composition contains iron as a main component and about 4.5−6% CR. This alloy is in addition alloyed with silicon and manganese at 0.5%. Additives of molybdenum, Nickel, tungsten and copper in the amount of not more than 1.5%, vanadium — 0.05%, carbon — 0.15% of titanium, 0.03 percent. Doping contributes to improve the heat resistance and gives the opportunity to produce the most important parts. When choosing heat-resistant steel, if not burdened working conditions, it is possible to change this brand to another, with lower carbon content. This steel has a relatively balanced performance of heat resistance and heat resistance, allowing very popular. When welding requires preheating to a temperature of 100−120°C, final heat treatment seams. The use of durable stainless steel pipes saves money and time on maintenance and repair. A significant advantage — no need to paint a protective pipe coating.

Production range of steel grade 15H5M produced using metal stamping under a predetermined shape. Circles of this steel can be used in the form of forgings, ie intermediate preform for different products.
