AISI 4140 4130 structure mild carbon/42crmo4  alloy steel round bar price for sale

We are specialized in the production and processing of metal raw material, such as carbon steel.
 

Round steel refers to long solid steel with circular section. Its specification is expressed in diameter.

Round steel is divided into hot rolling, forging and cold drawing. The specification of hot rolled round steel is 5.5-250 mm. Among them, 5.5-25 mm small round steel is mostly supplied in bundles of straight bars, which is often used as reinforcement, bolts and various mechanical parts; Round steel larger than 25 mm is mainly used for manufacturing mechanical parts, pipe blank of seamless steel pipe, etc. Difference between round steel and other reinforcement:
1. The appearance of round steel is different. The appearance of round steel is smooth and round, without lines and ribs, and the appearance of other reinforcement surfaces is engraved or ribbed.
2. The composition is different. Round steel belongs to ordinary low carbon steel, and other reinforcement is mostly alloy steel.
3. The strength is different. The strength of round steel is low and that of other steels is high, but the plasticity of round steel is stronger than that of other rebars.
