GNEE is a leading supplier of 904L stainless steel coils, offering cold-rolled 904L stainless steel coils in various thicknesses, shapes, and sizes, specifically designed for the manufacture of mechanical components.
AISI 904L BA cold-rolled stainless steel coils are a high-quality, high-alloy austenitic stainless steel, manufactured using cold rolling and annealing processes, resulting in a bright, mirror-like BA (bright annealed) finish. They can withstand maximum loads and temperatures, thus reducing the risk of accidents due to their inherent safety features. They are ideal for applications requiring high strength, formability, and aesthetics, such as chemical processing, marine engineering, and high-end appliances.
ASTM A240 and ASME SA 240 are some of the standards for these coils. They are available in a variety of standard sizes, with lengths ranging from 1000 mm to 6000 mm and thicknesses from 4.0 mm to 100 mm, and can be customized according to customer requirements. Customers can choose from different hardness levels, including soft, hard, semi-hard, quarter-hard, and spring-hard. The coils are coated with a plastic coating to prevent environmental damage.
What are 904L stainless steel coils edges?
Mill edge is a non-trimmed edge appearance after hot or cold rolling and annealing/pickling process. It usually leaved an irregular pinhole line on the edge side around 10mm to 15mm.Slit/slitting edge means we will trim irregular pinhole line on our slitting machine.
