Description

35 steel is used: for the manufacture of sheet metal, 1−2 mm 4−14 category, intended for cold forming; parts of low strength, experiencing a small voltage: axles, cylinders, crankshafts, connecting rods, spindles, sprockets, rods, rims, crossarms, shafts, tires, wheels and other parts; after hardening — for the manufacture of parts of pipeline fittings; packages of submersible electric motors and pumps for the oil industry; hot rolled profiles for the upper and lower rings of the turning circle of trailers; hot-rolled strip profile with a bias for agricultural machinery; seamless tubes for manufacture of parts and structures in motovelotehnika; solid-rolled rings for different purposes.

Note

The degree of deoxidation — SP.

Weldability Limited weldability. The welding methods of SMAW, ADS submerged arc and gas protection electroslag welding. Recommended heating and subsequent heat treatment. The CCC without restriction.
Propensity to temper brittleness Tend not.
Forging temperature Start - 1280 °C, the end - 750 °C. the Workpiece cross-section up to 800 mm are cooled in air.
Flock-sensitive sensitivity not sensitive.
Workability by cutting In hot rolled state at NV 144-153 and blower SB=510 MPa Kn TV.SPL.=1,3.
Surfacing Surfacing of sealing surfaces of valves in accordance with OST 26-07-2028-81 is made by manual arc welding electrodes type e-20X13 with plaster SSSI-13НЖ, NII-48, NII-48Ж-1 or SV wire-12H13 or SV-20X13. Surface preparation for overlay welding is performed by machining. Surfacing is performed with preliminary and accompanying heating to 400-450 °C is not less than 3 layers with thickness not less than 4 mm, excluding allowance for machining. Heat treatment after welding is produced by tempering at 550-600 °C (delay of 2-5 h) hardness HB=301-350, at 600-650 °C (delay of 2-5 h) hardness HB=240 to 300, at 400-450 °C (delay of 2-5 h) hardness HB=351-400. The temperature of the furnace when loading the details for the home should be no more than 300 °C.
