304 Stainless Steel Strip For Welded Pipe: The Complete Guide

304 stainless steel strip for welded pipe is the main material for welded tube production. If you are the beginner of this area, you can benefit from this guide.

By the end of this blog, you will have full understanding on all aspects of 304 stainless steel strip for welded pipe.

Let’s keep reading.

304 stainless steel strip has good weldability for welded pipe production.

Heat resistance means that 304 stainless steel strip can still maintain its excellent physical and mechanical properties at high temperatures conditions. So the high temperature does not influence the welded pipe properties during manufacturing process.

Compared with 201 stainless steel strip, 304 stainless steel strip has good corrosion resistance, low temperature strength and mechanical properties.

When the amount of chromium atoms in the steel is not less than 12.5%, the electrode potential of the steel can be abruptly changed from a negative potential to a positive electrode potential. Prevent electrochemical corrosion.

Many 304 stainless steel welded pipes are used in corrosion applications. So good corrosion resistance of tubes will be noticed.


When it comes to welded tubes production, cost-effective feature can be key. That’s why customers come to us when sourcing 304 stainless steel strip material for welded tubes application. We’ve got you covered.

What Is 304 Stainless Steel Welded Pipe?

Introduction Of 304 Stainless Steel Welded Pipe

The 304 stainless steel welded pipe is used in lots of industries where high temperature strength and better corrosion resistance is needed.

304 stainless steel welded pipe is also called 304 stainless steel welded tube.

Grade 304 stainless steel welded pipes raw materials are 304 stainless steel strips, these strips are welded and formed after being crimped by a unit and a mold.

304 stainless steel welded pipe has simple production process, high production efficiency, many varieties and specifications, and less equipment investment. But the general strength is lower than seamless stainless steel pipe.


Since the 1930s, with the rapid development of high-quality stainless steel strip continuous rolling production and the advancement of welding and inspection technology, the quality of welding pipe has been continuously improved, and the variety and specifications of welded pipes have increased, and in more and more fields, especially in heat exchange spare tubes, decorative tubes, medium and low pressure fluid tubes, etc. have replaced seamless steel tubes.

Features Of 304 Stainless Steel Welded Pipe

Small diameter stainless steel welded pipes are continuously produced in equipment lines.

The greater the investment in the unit and welding equipment with the more bigger wall thickness, and the less economical and practical it is.

The thinner the wall thickness, the input-output ratio will be lower.

The production process of the product determines its advantages and disadvantages.

Generally, the 304 stainless steel welded pipe has high precision, uniform wall thickness, and high brightness inside and outside surface finish of the pipe (the welded pipe is determined by the surface grade of the 304 stainless steel strip surface brightness).

It can be arbitrarily fixed length during production. Therefore, it embodies its economy and beauty in high-precision, medium and low-pressure fluid applications.

Types Of 304 Stainless Steel Welded Pipe

According to the weld form, 304 stainless steel welded pipe is divided into straight welded pipe and spiral welded pipe.

According to the purpose, it is divided into general welded pipes, heat exchanger pipes, condenser pipes, galvanized welded pipes, oxygen-blowing welded pipes, wire casings, metric welded pipes, roller pipes, deep well pump pipes, automotive pipes, transformer pipes, and electric welded thin-walled pipes. Pipe, electric welded special-shaped pipe and spiral welded pipe.

Hardness Index of 304 Stainless Steel Welded Pipe

304 stainless steel welded pipe is a basic pipe material, so it also has many necessary indicators of rigidity.

According to different test methods and applicable ranges, hardness can be divided into Brinell hardness, Rockwell hardness, Vickers hardness, Shore hardness, micro hardness and high temperature hardness.

What Are The Stainless Steel Welded Pipes Applications?

304 stainless steel welded pipe is a versatile stainless steel material with stronger rust resistance than 201 stainless steel welded pipe.

The high temperature resistance is also better, which can reach 1000-1200 degrees.

304 stainless steel welded pipe has excellent stainless corrosion resistance and good intergranular corrosion resistance.

Stainless steel welded pipes for mechanical structures are mainly used for machinery, automobiles, bicycles, furniture, hotel and restaurant decoration and other mechanical parts and structural parts.

Stainless steel welded pipes for fluid transportation, which are mainly used to transport low-pressure corrosive media.
