Heat-resisting steel wire, bar, rod X15CrNiSi25-20 wire, rod, bar, aisi 314

Manufacture

Heat-resistant steel of X15CrNiSi25−20 grade, aisi 314 relates to complex alloyed iron alloys. It consists of chrome — 24−27%, nickel -18−21%, molybdenum and copper — 0.3%, manganese — 1.5%, carbon, vanadium, tungsten, titanium — 0,2%, silicon — 2−3%, additives of sulfur and phosphorus — hundredths of percent. It is smelted in induction furnace. Jumping up temperature of semi-fabricates constitutes 1170 °C at the beginning and 850 °C at the end. Quenching is performed in air at a temperature of 1050−1150°C. Calibrated bar is made according to the following GOSTs: 7417−75, 8560−78 and 8559−75. Manufacture of brushed bar complies with GOST 14 955−77. Forging blankets are made according to GOST 1133−71. Percentage composition according to GOST 5632−72

Rod is made by stamping method — flow of metal to specific dimensions. Hot stamping is considered to be a cheaper, less complicated and energy-consuming method as long as there are needed fewer efforts for hot metal forming. There are stamped a few surfaces at the same time. That is why rod turns out to be smooth and uniform. Processing of multiple surfaces is more profitable — there is possible a manufacture of blankets with different sections due to a die with intended sizes. A finished bar section of X15CrNiSi25−20 grade in the forms of wire, rod or bar is cooled in air.

Application

It is used in products of high-temperature installations that operate in mechanical engineering, petrochemical industry. The following goods can be manufactured out of such rod and bar: rollers of thermal furnaces, furnace conveyors that are intended to operate at a temperature of up to 1000 °C and other parts of industrial high-temperature furnaces (parts of carburizing boxes that are intended to increase hardness and wear resistance of steel). During carbonisation, there is reached a temperature of 850−900 °C. Rod is widely used in textile industry and wire is applied for welding of steel.

Properties

A period of operational use of products is limited by a maximum temperature of 1000 °C. After this, there begins an extensive oxide scale formation. Heat-resistant pipe X15CrNiSi25−20, aisi 314 is resistant to corrosion in air and hot gas environments. Alloying with chrome, nickel, silicon, molybdenum, vanadium, tungsten allows withstanding contact with aggressive environment for a long time because while heating alloying additives form protective oxide films that prevent corrosion. Heat-resistant steel X15CrNiSi25−20, aisi 314 is fairly malleable. This allows making the most complicated constructions out of it.
