Product Overview

Our 0.6 mm and 0.8 mm ST14 cold-rolled low-carbon steel coils are highly representative of our cold-rolled steel range. ST14 is a deep-drawing grade of non-ageing steel, specifically designed for applications requiring severe plastic deformation without cracking, wrinkling, or surface defects.
These coils are produced using advanced cold-rolling processes and undergo bright annealing in a controlled hydrogen-nitrogen atmosphere, resulting in exceptional ductility and surface quality that fully meet the stringent requirements of automotive body panels, complex home appliance housings, precision stamped parts, and fine metal enclosures. The 0.6 mm and 0.8 mm thicknesses provide the optimal balance between lightweight design and structural integrity required for modern manufacturing.
The ST14 grade corresponds to the European DC04 and Japanese SPCE grades in the German DIN standard and has become the global benchmark for deep-drawing cold-rolled steel applications. Whether for stamping fuel tanks, forming door panels, or deep-drawing complex kitchen sinks, ST14 delivers the material consistency and reliability your production lines require.

Manufacturing Process

Every ST14 coil is produced through a precisely controlled six-stage process:
  1. Hot Rolled Substrate Selection — Premium low-carbon hot rolled strip selected for uniform chemistry and cleanliness
  2. Pickling — Hydrochloric acid removal of surface scale to prepare for cold rolling
  3. Cold Rolling — Thickness reduction at room temperature to achieve 0.6mm or 0.8mm with ±0.02mm precision
  4. Bright Annealing — Continuous annealing in hydrogen-nitrogen atmosphere at controlled temperatures to recrystallize the grain structure and restore ductility without surface oxidation
  5. Skin Pass Rolling — Light temper rolling to improve flatness, eliminate yield point elongation, and provide the desired surface texture

Primary Applications

Automotive Manufacturing
ST14 is the material of choice for complex automotive stampings including door outer panels, hoods, trunk lids, fenders, fuel tanks, and oil sumps. Its ability to undergo deep drawing and subsequent flanging operations without splitting makes it indispensable for modern vehicle body-in-white production.
Appliance & White Goods
Refrigerator door panels, washing machine drums, oven cavities, dishwasher tubs, and microwave enclosures benefit from ST14's ability to form tight radii and maintain surface integrity after severe deformation. The bright annealed finish also provides an excellent base for porcelain enameling or powder coating.
Metal Furniture & Fixtures
Office furniture shells, filing cabinet drawers, metal bed frames, and shelving systems requiring complex bends and drawn features. The non-ageing property ensures that formed components remain stable and do not become brittle during storage or transport.
Electrical & Electronic Enclosures
Switchgear housings, control panel cabinets, server chassis, and junction boxes where precise bending and drawing are combined with welding operations. ST14's low carbon content ensures excellent weldability with minimal risk of cracking in the heat-affected zone.
Food & Beverage Packaging
Deep-drawn food cans, aerosol containers, and complex metal packaging where material must undergo severe forming while maintaining food-grade surface cleanliness.

FAQ

Q: What is ST14 steel and how does it differ from regular cold rolled steel?

A: ST14 is an extra deep drawing quality cold rolled steel grade defined under the German DIN 1623 standard. Unlike commercial quality cold rolled steel (such as ST12 or SPCC) which is suitable only for simple bending, ST14 is engineered with ultra-low carbon content and special annealing to withstand severe forming operations where the drawn depth exceeds the part diameter. It offers significantly higher elongation (36–38% vs 28–32% for commercial grades) and superior resistance to necking during deformation. If your application involves deep drawing, stretching, or complex stamping, ST14 is the appropriate grade.

Q: What coil widths are available? Can you slit the material to custom dimensions?

A: Our standard stock widths are 1000 mm, 1219 mm, and 1250 mm. We offer precision slitting services for widths of 600 mm and above, with a typical tolerance of ±0.5 mm. Custom slitting eliminates waste generated by internal cutting and ensures the coil width perfectly matches your press feed width. Common slitting widths for automotive stamping lines include 800 mm, 1000 mm, and 1150 mm. Please specify the required width when requesting a quote.

Q: Are you trading company or manufacturer ?

A: We are manufacturer, and We are the factory for Metal Steel Fabrication, Laser Cutting, Bending, Welding, Material Cutting into Length, Machining, all Types of Structures and parts can be produced based on your drawings.
