Product Description

The main grades and specifications of carbon steel rod materials

1. Hot rolled steel bars: Hot rolled steel bars are divided into different grades and specifications such as low-carbon steel, medium carbon steel, and high carbon steel. Among them, low-carbon steel rods (such as Q235B) are widely used in fields such as building structures, bridges, and ship load-bearing; Medium carbon steel rods (such as 45 # steel) are suitable for mechanical parts, bearings, etc; High carbon steel rods (such as 55 # steel) are used to make components with high strength requirements such as springs.

2. Cold drawn steel bars: Cold drawn steel bars are made through cold processing technology, with a smooth surface, precise dimensions, and high strength. Cold drawn steel bars are widely used in fields such as automobiles, machinery, aerospace, etc.

3. Forged steel bars: Forged steel bars are divided into different types such as alloy steel, carbon steel, bearing steel, tool steel, etc.
