ГОСT 4543 -1971 Material Specification for Steel Round bar 35Г2 Steel forgings, Plate stock available 35Г2 Hot blooming / rolling / forging, Heat treatment
 
MATERIAL DESIGNATION - 35Г2
Material category:  middle-carbon 1.6%Mn steel
Material specifications: ГОСT 4543 -1971
Available in stock: round bar diam. 20 ~ 140mm

PRODUCT DESCRIPTION
The 
alloy is usually produced by EAF + VD + LF / BEF followed by electroslag refining (ESR) if necessary for special purpose. Bars and, where applicable, forgings are subjected to ultrasonic examination based on the different level according to the buyers' requirements.
Bars are usually supplied bright in the annealed condition, or bright annealing specially.
Final heat treatment - Quenched and tempered. 
Rod / round bar / disc (diameter): 5.5 ~ 800mm
Square bar & flat bar: 8 ~ 610mm
Plate & Sheet: cold & hot rolled / forged T 2.0 ~ 300 X W 10 ~ 1200 X L mm
