Working with 10G2S1-CD
Is 10G2S1 easy to machine?
Machines like a 350 MPa-yield HSLA steel at ~55–60 % of AISI 1212; the ~1 % Si makes chips gummy, so use sharp coated carbide, positive rake and generous feed to avoid work hardening.
Can 10G2S1 be welded?
Weldable without restriction by MMA/MAG/SAW with low-hydrogen basic consumables; preheat 100–150 °C above ~30 mm or below 0 °C ambient and control interpass heat input to protect −70 °C toughness.
Can 10G2S1 be formed, bent or molded?
Good cold bending and press-braking with bend radii ≥2t; hot forming 850–1150 °C followed by normalizing restores toughness after heavy deformation.
What surface finishes work on 10G2S1?
No natural corrosion resistance — shot-blast to Sa 2½ then epoxy/polyurethane paint, hot-dip galvanize or thermal spray; phosphating suits fasteners and machined parts.

10G2S1-CD — frequently asked
What is 10G2S1-CD used for?
10G2S1-CD is typically used for cold-climate structures, machinery frames and pipe fittings. In short: cold-tough GOST HSLA; higher strength than 09G2S; weldable down to -70 °C service.
What is the yield strength of 10G2S1-CD?
10G2S1-CD has a typical yield strength of 480 MPa (69.6 ksi) and a tensile strength of 580 MPa (84.1 ksi) — stronger than 59% of steel grades. Strength varies by condition: see the 5 listed tempers.
Is 10G2S1-CD easy to machine?
Reasonably — machinability is rated good (55/100, better than 62% of steel grades). Machines like a 350 MPa-yield HSLA steel at ~55–60 % of AISI 1212; the ~1 % Si makes chips gummy, so use sharp coated carbide, positive rake and generous feed to avoid work hardening.
Can 10G2S1-CD be welded?
Yes — weldability is rated very good (74/100). Weldable without restriction by MMA/MAG/SAW with low-hydrogen basic consumables; preheat 100–150 °C above ~30 mm or below 0 °C ambient and control interpass heat input to protect −70 °C toughness.
What surface finishes work on 10G2S1-CD?
No natural corrosion resistance — shot-blast to Sa 2½ then epoxy/polyurethane paint, hot-dip galvanize or thermal spray; phosphating suits fasteners and machined parts.
Can 10G2S1-CD be formed, bent or molded?
Good cold bending and press-braking with bend radii ≥2t; hot forming 850–1150 °C followed by normalizing restores toughness after heavy deformation.
What is the maximum service temperature of 10G2S1-CD?
10G2S1-CD is rated for continuous use to about 400°C (752 °F). Strength falls off well before that limit — check the elevated-temperature data for load-bearing parts.
What is the difference between 10G2S1-HR and 10G2S1-CD?
HR is the default condition — default mill condition for welded structural plate and sections at strength class 345. CD: pick for close tolerance bar or strip where extra strength and surface finish matter more than ductility. Yield strength is 360 MPa in HR versus 480 MPa in CD.
