02Н18К9М5Т - эп637 sheet, round, wire
Brand 02Н18К9М5Т-ID refers to a group of steels of Maraging type. Is melted in a vacuum induction furnace. Produced in accordance with the following specifications: 14−1-4896−90, 14−1-2227−77; 14−1-1531−75; 14−1-3039−80 and fully meets the strict requirements of the state standard. Are made these types of rentals: circle, tube, wire, sheet, ribbon. During plastic deformation in the initial stage temperature is 1170 °C, and the end — of about 900 °C. This steel can easily succumb to cutting, used in the manufacture of parts with high loads, for bolts, axles, tanks, pins, etc. of fasteners.

— Induction of saturation is 10−12 kgs
— Elastic modulus of 18.6 · 10— 4 N/mm2
— The specific electrical resistance is 0,38 — 0,39, Mhmm2/m
— The hardness of the steel is 200 MPa -1 NV.
— Coefficient of thermal linear expansion of 10.1x10-6/°C
— Magnetic permeability in a field of 500 e равна1,255 micro Tesla/m.
The pipes are manufactured as seamless — seamless and welded — welded. The circle is made by stamping metal under a predetermined shape, often used in the form of forgings, ie intermediate preform for different products. Sheets rods supply without heat treatment. Technical documentation for delivery of metal ensures standards of quality control of the alloy:
— chemical composition of alloying elements;
— maximum content of impurities;
— ultrasonic testing for the absence of cracks;
— dimension tolerance, surface quality, curvature.
With automatic and manual TIG welding. In the process of manual arc welding electrodes are used with wire rod of steels SV — 02Н18К9М5Т-ID.
Steel 02Н18К9М5Т-ID demonstrated high reliability, it is resistant to intergranular corrosion and to stress corrosion cracking in alkaline and chloride environments. The doping increases the heat resistance allows details to installations of the power type. This steel has the balanced qualities of heat resistance and heat resistance, whereby so popular. It was the most widely used in the manufacture of parts with high loads, for bolts axles, pins and other fasteners, as well as for containers that operate in environments of increased aggressiveness at temperatures up to 80 °C.
