1/2 Hard Stainless Steel Coil

1/4 Hard Stainless Steel Coil, also known as semi-hard stainless steel coil, is a stainless steel coil produced through cold rolling at a specific reduction rate. Its hardness falls between the soft state (2B surface) and the fully hard state, retaining good formability and weldability while possessing higher strength and rigidity than the soft state. It meets the needs of medium-strength processing scenarios without secondary hardening treatment, avoiding problems such as cracking due to excessive hardness or insufficient strength due to excessive softness.

New Energy Field: Used in fuel cell bipolar plates and battery casings, requiring high conductivity, corrosion resistance, and a certain degree of formability. The 1/2 hardness perfectly matches processing requirements, ensuring component stability.

High-end home appliance sector: Washing machine drums, dishwasher inner walls, refrigerator frames, etc., require corrosion resistance, wear resistance, and aesthetic appeal. Surface finishes can be customized to match the high-end positioning of these appliances.

Architectural decoration sector: Building curtain walls, door and window frames, ceiling decorations, etc., require complex curved surface bending processing, moderate hardness to prevent deformation, and good weather resistance, suitable for both interior and exterior decoration scenarios.

Automotive manufacturing sector: Automotive interior parts, exhaust pipe accessories, and body trim parts require a balance of strength and formability. 1/2 hard stainless steel coils can meet the processing needs of stamping and bending, improving the durability of automotive components.

Chemical and marine sectors: 316L 1/2 hard stainless steel coils, due to the addition of molybdenum, possess excellent resistance to pitting and crevice corrosion, suitable for harsh environments such as chemical equipment and marine engineering components.

Q1: What is the difference between 1/2 hard stainless steel coils and soft/fully hard stainless steel coils?

A1: Soft stainless steel coils have good formability but low strength, fully hardened coils have high strength but poor formability, and 1/2 hard (semi-hard) coils fall between the two, balancing good formability and moderate strength. They do not require secondary hardening and are suitable for processing scenarios requiring moderate bending and stamping, making them one of the most cost-effective choices.
Q2: What is the minimum order quantity? Can I purchase in small batches?
A2: The standard minimum order quantity is 1 ton. Small batches (less than 1 ton) are negotiable. We support small-batch trial orders so you can confirm the quality before making large-batch purchases, reducing procurement risks.
Q3: Are the products internationally certified? Can they be exported?
A3: Our 1/2 hard stainless steel coils have passed ISO, CE, ASTM, and other international certifications and can be exported normally. We support various trade terms such as FOB and CIF, and provide complete export customs documents. Our products have been exported to Dubai, the United States, Europe, Southeast Asia, and many other countries and regions.
Q4: What happens if there are quality problems with the product?

A4: We promise that if there are any quality issues with the product, such as material, hardness, or size, you can contact us within 7 days of receiving the goods. We will arrange for professional personnel to verify the issue. Once the problem is confirmed, we will cover the round-trip shipping costs and quickly replenish the goods, or provide a full refund to protect your legal rights.
