Product Description

Carbon Steel Cold Drawn Bar
All bars are cleaned by shot blasting before drawing, then pulled through a carbide die, straightened, saw cut to length, oiled, and shipped. Cold drawing results in a product with higher tensile and yield strength, smoother surface finish, and a closer size tolerance.
Cold Drawn Steel Bar Processing:
EAF + LF + VD + CONCASTING BILLETS + HOT ROLLED + SHOT BLASTING + (ANNEALING) + COLD DRAWN + OILING + BUNDLING + BOTH ENDS CUTTING + PACKING + MARKING

Frequently Asked Questions

Q1: What are the main benefits of SAE 1045 cold drawn steel?

A: It offers higher tensile and yield strength, a smoother surface finish, and much tighter dimensional tolerances compared to hot-rolled steel.

Q2: What shapes are available for cold drawn steel?

A: We provide Round, Square, Hexagonal, and various special profiles to meet diverse industrial requirements.

Q3: What is the typical straightness of your steel bars?

A: The standard straightness for our cold drawn steel bars is a maximum of 0.8mm/m to 1mm/m, ensuring suitability for automatic CNC feeding.

Q4: What size range can you manufacture?

A: We produce sizes ranging from M12 to M120, with round bars available from 5mm up to 120mm in diameter.

Q5: How is the steel protected during transport?

A: All bars undergo anti-rust oiling and are packed using sea-worthy, anti-rust materials to ensure they arrive in perfect condition.

Q6: What quality inspections are performed?

A: We utilize a full range of equipment including UT testing, tensile and hardness testers, spectrometers, and metallographic microscopes.
