OEM SUS304L Austenitic Spring Steel Strips / coil for stainless steel etching materials

SUS304L cold rolled stainless steel strip with  thickness:0.05-0.8mm  width:4-600mm  Thickness tolerance: 0.005mm HV160-400  Surface:2B BA                  

Applications:

Mainly used for Electronics, computer accessories, stationery, kitchen utensils, medical equipment, stainless steel etching materials, chemical packing, needle material,spiral wound gasket, seal.

Applied to the high resistance to intergranular corrosion, chemical, coal, petroleum environment instruments and equipment; outdoor decorative materials, heat-resistant parts and heat treatment difficult parts. Frozen Container Frame and exterior materials, car exhaust pipe (800 ℃), heat-resistant equipment parts.

Description:

304L stainless steel in the 304 stainless steel on the basis of low-carbon, increased content of nickel and chromium, the development of 304L stainless steel, has corrosion resistance, elongation, appearance, workability, strength, and other characteristics of the 304L stainless steel is far more than the other materials,Moreover, the stainless steel surface treatment method, you can obtain a variety of colors and shapes, which makes a significant contribution for the development of the stainless steel.

Austenitic steels, uses the most widely used, excellent corrosion resistance, heat resistance, low temperature strength and mechanical properties, single-phase austenite hardening heat treatment (non-magnetic, temperature-196-8000C). With SUS304 all characteristics, corrosion resistance and excellent heat resistance; after welding or eliminate stress, can also maintain good corrosion resistance, drawability, excellent polishing properties.SUS304L with SUS304 all features; excellent in corrosion resistance and heat resistance; or eliminate stress, able to maintain good corrosion resistance after welding; deep drawability and excellent polishing properties.
