Carbon Steel

Q: Q1: What carbon steel grade is best for welding?

A : Low-carbon steels (e.g., AISI 1018, ASTM A36) offer excellent weldability due to minimal carbon content.

Q: Q2: Can you supply carbon steel for cryogenic applications?

A : Yes, ASTM A516 Gr.70 (low-temperature carbon steel) is ideal for LNG tanks and subzero environments.

Q: Q3: Do you provide anti-corrosion treatments for carbon steel?

A : We offer galvanizing, epoxy coating, and zinc plating to enhance corrosion resistance.

Q: Q4: What is the minimum order quantity (MOQ)?

A : MOQ starts at 1 ton; bulk orders receive discounted pricing.

Q: Q5: How do I verify material authenticity?

A : All shipments include EN 10204 3.1 MTCs with heat numbers for full traceability.
