Description

Additional Information

?Grade Standard?: High-quality carbon structural steel under Chinese standard (GB/T 699-2015), with carbon content approximately 0.47%-0.55%5.
?Mechanical Properties?:
- Tensile strength ≥630 MPa, yield strength ≥375 MPa, elongation ≥14%5.
- High hardness (HB 170-210), but relatively low impact toughness5.
?Machinability?: Suitable for cutting, forging, welding, etc., but poor cold formability5.

?Mechanical Manufacturing?:
- Gears, shaft components (machine tool spindles, engine crankshafts)5.
- Wear-resistant parts such as rollers, tie rods, spring washers5.
?Molds and Tools?:
- Cold work molds (punches, dies), suitable for small batch stamping of soft low-carbon steel plates5.
?Construction and Engineering?:
- Steel structure connectors, hot-pressed forgings, seamless steel tubes5.

?Comparison with Bearing Steel?: Slightly lower wear resistance but significant cost advantage5.
?Comparison with Alloy Steel?: Suitable for scenarios requiring high strength but low impact loads5.
