Widely used in machinery manufacturing, construction industry, metallurgical industry, agricultural vehicles, agricultural greenhouses, automobile industry, railways, highway guardrails, container skeletons, furniture, decoration and steel structures. In addition, with the same bending strength and torsional strength, it is lighter in weight, so it is also widely used in the manufacture of mechanical parts and engineering structures. It is also commonly used in the production of various conventional weapons, barrels, shells, etc.
Note:
1.Free sampling, 100% after-sales quality assurance, Support any payment method;
2.All other specifications of round carbon steel pipes are available according to your requirement (OEM&ODM)! Factory price you will get from ROYAL GROUP.

Stainless Steel Bar Surface Finish
Through different processing methods of cold rolling and surface reprocessing after rolling, the surface finish of stainless steel bars can have different types.
The surface processing of stainless steel pipes have NO.1, 2B, No. 4, No. 3, No. 6, BA, TR hard, Rerolled bright 2H, polishing bright and other surface finishes, etc.
NO.1
Processing type: hot rolling, annealing, removing oxidized skin
State characteristics: rough, dark
2D
Processing type: cold rolling, heat treatment, pickling or phosphorus removal
State characteristics: The surface is uniform, matte
2B
Processing type: cold rolling, heat treatment, pickling or phosphorus removal, bright processing
State characteristics: The surface is smooth and straight compared with 2D
BA
Processing type: cold rolling, bright annealing
State characteristics: smooth, bright, reflective
3 #
Type of processing: Brush film or matte finish on one or two sides
State characteristics: no direction texture, no reflection
4 #
Type of finishing: General finishing for single or double sides
State characteristics: no direction texture, reflective
6 #
Processing type: single or double matte satin line polishing, Tampico grinding
Condition characteristics: matte, no direction texture

Process of Production
The production process of stainless steel pipe needs to go through: stapling → calendering → annealing → slicing → pipe making → polishing
1. Tape booking: Prepare raw materials of steel tape in advance according to demand
2. Calendering: Use calendering machine to press the roll plate like rolling noodles and roll the roll plate to the required thickness.
3, annealing: due to the rolling plate after calendering, physical properties can not reach the standard, toughness is not enough, need to annealing, restore stainless steel properties.
4. Strip: According to the outer diameter of the pipe produced, strip it
5. Pipe making: Put the divided steel strip into the pipe making machine with different pipe diameter molds for production, roll it into the corresponding shape, and then weld it
6. Polishing: After the pipe is formed, the surface is polished by the polishing machine.
Packaging is generally naked, steel wire binding, very strong.
If you have special requirements, you can use rust proof packaging, and more beautiful.
