Product introduction

Stainless steel rectangular bar

The stainless steel bar has a smooth surface, high plasticity, toughness and mechanical strength, and is 

resistant to corrosion by acids, alkaline gases, solutions and other media. It is an alloy steel that does not 

rust easily, but not absolutely rust-free.


1. Weldability

Different product uses have different requirements for welding performance. A class of tableware generally 

does not require welding performance, and even includes some pot enterprises. However, most products 

require good welding performance of raw materials, such as second-class tableware, thermos cups, steel 

pipes, water heaters, water dispensers, etc.

2. Corrosion resistance

Most stainless steel products require good corrosion resistance, such as Class I and II tableware, kitchen 

utensils, water heaters, water dispensers, etc. Some foreign merchants also do corrosion resistance tests on 

the products: use NACL aqueous solution to heat it to boiling, and pour it after a period of time. Remove the 

solution, wash and dry, and weigh the weight loss to determine the degree of corrosion (Note: When the 

product is polished, the Fe content in the abrasive cloth or sandpaper will cause rust spots on the surface 

during the test)

3. Polishing performance

In today's society, stainless steel products are generally polished during production, and only a few products 

such as water heaters and water dispenser liner do not need polishing. Therefore, this requires that the 

polishing performance of the raw material is very good. The main factors that affect the polishing performance 

are as follows:

(1)Surface defects of raw materials. Such as scratches, pitting, pickling, etc.

(2)The problem of raw materials. If the hardness is too low, it will not be easy to polish when polishing (the BQ 

property is not good), and if the hardness is too low, the orange peel phenomenon is easy to appear on the 

surface during deep drawing, thus affecting the BQ property. BQ properties with high hardness are relatively good.

(3)For the deep-drawn product, small black spots and RIDGING will appear on the surface of the area with a large 

amount of deformation, thus affecting the BQ performance.

4. Heat resistance

Heat resistance means that stainless steel can still maintain its excellent physical and mechanical properties at 

high temperatures.

Influence of carbon: Carbon is an element that strongly forms and stabilizes austenite and expands the austenite 

region in austenitic stainless steels. The ability of carbon to form austenite is about 30 times that of nickel, and 

carbon is an interstitial element that can significantly increase the strength of austenitic stainless steel through 

solid solution strengthening. Carbon can also improve the stress  corrosion resistance of austenitic stainless steel 

in highly concentrated chloride (such as 42% MgCl2 boiling solution).

Advantage

1. Selected materials carefully: high strength, good pressure bearing, firm and pressure resistance, 

smooth and beautiful inside and outside, not easy to be deformed by force

2. The cut surface is smooth: no burrs, no hand cutting, equipped with good equipment and craftsmanship 

and a skilled technical team

3. Complete specifications: sufficient inventory, non-standard products support cutting and customization, 

and provide cutting, drilling, surface and other processing technologies

4. Quality Assurance: Strict quality inspection at outgoing warehouse, only qualified inspection can leave 

the factory

5. Wide range of applications: industrial industry, automobile industry, machinery manufacturing, construction 

engineering, ship construction, aviation manufacturing, etc.

 

Application

Due to the many great features of stainless steel, it is widely used in many industries. It includes constructions, 

home appliances, automobiles, kitchen accessories, mechanical structure, decoration engineering, chemical 

industry, etc. Let's have a brief review.

1. Construction & Buildings

It is an essential building material widely used in commercial buildings, bridges, airports, etc. The most common 

uses include structural frames, roofing, wall panels, claddings, door panels, backsplash, handrailings, ceilings, 

elevator hall, inner panels of elevators, etc. Also, it is perfect for making handicrafts.

 

2. Automobile

Different grades of stainless steel can be used to manufacture car bodies, grills, trims, wheel axles, bearings, 

vehicular exhaust, fuel tanks, etc.

 

3. Industrial Uses

Stainless steel is ideal for transporting chemicals, liquids, etc. It is typical for medical uses, gas and oil industries, 

such as pipelines and tubes, blades, operation tables, pumps, processing or storage tanks & vessels, etc.

 

4. Household Appliances

About 75% of household appliances are made of stainless steel, including internal panels of cookers, heaters, 

ovens, burners, conveyors, grills, television, washing machine, refrigerator, kitchen hardware, etc.

 

5. Furniture & Daily Uses 

Stainless steel coil and sheet are also versatile in our daily life, such as trash cans, screens,benches, tables, beds, 

bookshelves, advertising boards, display stands, etc.
