Description
Relaksatsionnostoyky heat steel 30XMA. Relaksatsionnostoyky heat steel 30XMA is applied to creation of various parts and products: • Rotors and shaft; • Bolts and nuts; • Flanges and forgings of general purpose; • Disks of steam turbines; • Pipes for the chemical equipment; • Billets; • Bars and pins. The range of steel 30XMA corresponds: hot-rolled square – GOST 2591-88, hot-rolled square – GOST 2590-88, hot-rolled hexagon – GOST 2879-88, hot-rolled strip – GOST 103-76, shod round and square – GOST 1133-71, calibrated round – GOST 7417-75, calibrated square – GOST 8559-75, calibrated hexagon – GOST 8560-78, silver steel – GOST 14955-77 Relaxation steel 30XMA has the lowest creep and high elasticity of a crystal lattice. These properties allow to apply with success heat relaxation resisting steel at production of springs, pins, bolts, the fixing elastic brackets and other parts expected operation at temperature conditions to 500 C. In the chemical composition steel 30XMA contains chemical elements in %: silicon (Si) of 0.17-0.37%; manganese (Mn) of 0.40-0.70%; copper (Cu), no more than 0.30%; molybdenum (Mo) of 0.15-0.25%; nickel (Ni), no more than 0.30%; sulfur (S), no more than 0.025%; carbon (C) of 0.26-0.33%; phosphorus (P), no more than 0.025%; chrome (Cr) 0.80-1.10. Heat resisting call material which can sustain influence of high temperatures, without losing at the same time the mechanical strength. Physical, technology and mechanical properties of steel 30XMA: Heat treatment: Tempering 880oC, oil, Issue 540oC, water, Hardness of material: HB 10-1 = 229 MPas Temperature of critical points: Ac1 = 757, Ac3(Acm) = 807 Bondability of material: restrictedly welded. Flokenochuvstvitelnost: it is sensitive. Tendency to temper brittleness: it is not inclined. Use of steel 30XMA in the industry: for production of forgings of general purpose, rotors and disks of the steam turbines, flanges, gear wheels, bolts and different other parts working at a temperature up to 450-500 ºС; for production of parts of pipeline armature with carrying out heat treatment; pipes for installations of chemical and petrochemical productions with the conditional pressure of Ru of =19,6-98 MPas (200-1000 kgfs \sm.kv.) ; seamless pipes for production of parts and designs in a motovellostroyeniye. Circles, hexagons, square, strip, forgings and forgings, pipes. Buy the Forging round 30XMA legko:1. You send zayavku2. We expose to you schet3. You pay convenient for you sposobom4.
