Description:

321 square tube,it is a form of tube type.A lot of kinds of material of material can make the pipe body.It is medium in, what, in what place.Most of the square tube steel tube as the majority.For square tube structure, more decorative tube, architects, etc.

321 square tube, is a kind of square steel tubes, also is the equal of the steel tube length.It is the strip steel rolled through the process.Generally is the strip after unpacking, smooth, curly, form circular tube welding, again by circular tube rolling into square tube and then cut into required length.It is generally 50 per package.

321 square tube can be seamlessly and weld.Seamless pipe is seamless tube extrusion.

1,The performance index analysis - plastic square tube

Plastic refers to metal materials under loading, the plastic       deformation (permanent deformation) and does not destroy the ability.

2,The performance of the square tube - hardness index analysis

The pointer to the hardness was measured degree of hard and soft metal materials.At present in the production of measuring hardness method is pressed into the hardness of the most commonly used method.It is to use a certain geometry head to a certain load tested down into the surface of the metal material, according to the degree by the determination of the hardness value.The commonly used methods are brinell hardness (HB) and rockwell hardness (HRA, HRB, HRC) and vickers hardness (HV) and other methods.

The product is used for:Building high pressure and ultra-high voltage power plant boiler, the construction of superheated steam pipe, water pipe and locomotive boiler superheated steam pipe.
