Heat Resistant Parts Hot Rolled Low Carbon Steel Coil 304J1 6 Tons - 12 Tons Weight

Introduction to 304, 304L and 304J1:

304

A common austenitic steel with good corrosion resistance, thermal resistance, mechanical properties, and nonmagnetic

Application: Architecture, Decoration, Chemical industry, food processing equipment, Medicine, Fiber industry and Auto components

304L

Low-carbon type of 304 with all qualities of 304, also with excellent inter-granular corrosion resistance and weldablity

Application: Chemical, Coal, Petroleum and Nuclear energy industries, the heat-resistant parts and the parts that are difficult to make heat treatment after welding

304J1

Austenitic stainless steel, nonmagnetic,

Lower contents of Ni compared with 304, low cost;

Excellent formability and deep drawability with the addition of Cu;

Similar tensile strength and corrosion resistance to conventional 304

Application: with excellent formability and weldability, 304J1 can be widely used in Kitchen utensil, electrical appliance, construction decoration and other aspects. It’s a new grade with multi-functions

Chemical Composition

Mechanical Properties

304 Grade Stainless steel-Finishes-applications:

NO.1
Hot rolled, annealed, pickled, normally used as cold rolled material, industrial tanks and devices for chemical industry, etc
NO.2D
Cold rolled, annealed, pickled and dull finish products. Mainly used as automotive components; deep drawing parts, building components and pipes, etc.
NO.2B
Cold rolled, annealed, pickled, and skin-passed to give an appropriate luster at final stage. Their glossiness and flatness are better than No.2D products. They can be competent for almost all the applications of cold-rolled stainless steel, such as kitchen and bathroom ware, surface polishing, furniture structural parts, etc.
NO.3
The products achieved by grinding of No.2D surface with No.100~120 grinding belt. They have better glossiness and discontinuous coarse grain, and are used in inside and outside decoration of buildings, electrical appliance and kitchen installation, etc.
NO.4
The products achieved by grinding of No.2D surface with No.150~320 grinding belt. They have better glossiness and discontinuous coarse grain, but their grain is finer than No.3. They are used in elevator decoration, kitchen installation, inside and outside decoration of buildings, electrical appliance front panel, etc.
HL
The products achieved by continuous grinding of No.2D surface with polishing abrasive belt with appropriate grain size. They have relatively long
