S275JR/S355JR EN High quality carbon steel plate
S275 carbon steel is a kind of carbon structural steel, with high strength, good plasticity and machining performance, certain welding performance, small parts can be hardened and strengthened, more used in the manufacture of high strength parts, such as gears, shafts, sprockets, keys, bolts, nuts, agricultural machinery steel, conveyor chain and chain link.

Product details

S275JR is a carbon structural steel and low alloy structural steel for engineering and structural steel and is usually delivered without heat treatment. This kind of steel is similar to the steel numbers listed in GB/T700 and GB/T1591 in China, and is also carbon structural steel and low alloy structural steel for engineering and structural steel, and is usually delivered without heat treatment. S275 is equivalent to Q275.

Q275, is a kind of carbon structural steel, with high strength, good plasticity and cutting performance, certain welding performance, small parts can be quenched and strengthened, mostly used in the manufacture of parts requiring high strength, such as gears, shafts, sprockets, keys, bolts, nuts, agricultural machinery steel, conveyor chains and chain joints.

S355JR is a low alloy high strength structural steel in accordance with the European standard EN10025. S355JR steel in China is a low-alloy high-strength structural steel with a hardness of 70-80B and a yield strength between 300-400MPa.
