Question:

Stainless steel welded pipe or seamless pipe expensive?

Stainless steel welded pipe or seamless pipe expensive?

Answer:

Another important factor is the type of steel, specifications, such as thin plate than the middle plate expensive, thin-walled tube than thick walled pipe expensive, seamless pipe than welded pipe expensive, and so on.
From the brand can understand: domestic grade Cr smaller numbers are more expensive, the sum of Cr after the larger the number the more expensive, more expensive Cr symbols and so on. Foreign steel also has some rules: such as the stainless steel, the same series of numbers of bigger, longer, more expensive and more letters.
Stainless steel is generally divided into three categories: martensitic stainless steel, ferritic stainless steel, austenitic stainless steel, duplex stainless steel and precipitation hardening stainless steel. The price is roughly the same order as stainless steel. But each category has a cheaper and more expensive one, and the difference can be great.
