What Are Hot Rolled Stainless Steel Strips
Hot rolled stainless steel strip is a strip with a thickness of 1.80mm to 6.00mm and a width of 50mm to 1200mm produced by a hot rolling mill.
Hot rolled stainless steel material has many advantages such as low hardness, easy processing and good ductility.
The hot rolled stainless steel strip is made of hot rolled stainless steel coil after further hot rolling and slitting.
Its production process includes pickling, high temperature rolling, process lubrication, annealing, smoothing, cutting and packaging.
Compared with cold rolled stainless steel strip, it has higher dimensional accuracy, low surface roughness, good surface quality and high strength.
Therefore, thinner hot rolled strips can be used in place of thicker cold rolled strips for the same purpose to save stainless steel consumption, which has great economic significance.
Hot rolled stainless steel strips are divided into main five types according to their organizational characteristics: austenite, austenite-ferrite, ferrite, martensite and precipitation hardening, which can be selected in real application.
What Are The Difference Between Hot And Cold Rolled Stainless Steel Strips
At first, the yield strength of cold rolled stainless steel strips are better than hot strips, but and the malleability and toughness of hot rolled stainless steel strip is better.
Then, the thickness of cold rolled stainless steel strip is ultra-thin, while the thickness of hot rolled stainless steel strip is a bit thick.
At last, for the surface finish quality, appearance and dimensional accuracy of cold rolled stainless steel strip is better than hot rolled stainless steel strip.
What Is Hot Rolled Stainless Steel Strip Surface Treatment
Through different processing methods of cold rolling and surface reprocessing after cold rolling, the surface finish of stainless steel can have different types.
The surface processing of hot rolled stainless steel strips have NO.1, 1C, 1D, etc.
No. 1 surface finish is the refers to the surface obtained by heat treatment and pickling after hot rolling of the stainless steel coil.
It’s a common type of surface in most industry application.
It is to remove the black oxide scale produced during hot rolling and heat treatment by pickling or similar treatment methods.
This is No. 1 surface processing. The No.1 surface is silvery white and matt. Mainly used in heat-resistant and corrosion-resistant industries that do not require surface gloss, such as alcohol industry, chemical industry and large containers.
What Are The Advantages Of Hot Rolled Stainless Steel Strips
Hot rolled stainless steel strip has low hardness, easy processing and good ductility.
The mechanical properties of hot rolled stainless steel strip is far inferior to cold working, and inferior to forging, but it has better toughness and ductility.
What Are Hot Rolled Stainless Steel Strips Packaging
One kind of packaging is called wooden pallet. And the fumigation wooden pallets and non-fumigation pallets are two kinds of pallets type.
Eye to eye or eye to wall types of packaging hot rolled strips will be adopted before shipment.
The surface finish of hot rolled strips will be packaged with waterproof paper. Then coating the PVC film on this paper.
After that, the banding strap will be used for fastening pallets and metal strips products.
Before placing the metal strips into the wooden case, the strips are packaged with perfect packaging.
Wooden case and four corners shall not be smaller than the outer diameter of the total strips.
In addition, clear labels are tagged on the outside of these sea standard packages for easy identification of these hot rolled stainless steel strips specifications and quality information.
