S235JR/S275JR/S355JR/S355JO steel angle
S235JR angle steel: It is a low carbon steel with a yield strength of about 235MPa. It has a low yield strength, but its good plasticity and toughness make it perform well under medium loads and low temperature conditions. S275JR angle steel: It is a low alloy high strength structural steel with a yield point of not less than 275MPa, moderate strength and hardness, moderate strength and good processing performance. S355JR angle steel: It has high strength, a yield point of not less than 355MPa, can withstand large loads and high stresses, has high strength and hardness, and has the best mechanical properties.
