304 stainless steel square tube :


A square pipe is a name for a square pipe, that is, a steel pipe with equal sides. It is made of rolled steel after processing. Generally, the strip steel is unpacked, flattened, crimped, and welded to form a round pipe, which is then rolled into a square pipe and then cut to the required length.

Square tube is divided into seamless and welded seam. Seamless square tube is formed by extruding seamless round tube.

1. Performance Index Analysis of Square Tube-Plasticity

Plasticity refers to the ability of a metal material to undergo plastic deformation (permanent deformation) without damage under the load.

2. Performance Index Analysis of Square Tubes-Hardness

Hardness is a pointer for measuring the hardness of metal materials. The most commonly used method for measuring hardness in production is the indentation hardness method, which uses an indenter of a certain geometric shape to press the surface of the metal material under test under a certain load, and determines its hardness value according to the degree of indentation.

Common methods include Brinell hardness (HB), Rockwell hardness (HRA, HRB, HRC) and Vickers hardness (HV).

 

304 stainless steel square tube Grading and craft:


Surface grade

stainless steel has the following conditions, the status is different, and the dirt resistance and corrosion resistance are also different.

NO.1, 1D, 2D, 2B, N0.4, HL, BA, Mirror, and various other surface treatment states.

Feature processing

1D—The surface has discontinuous granules, also known as matte surfaces. Processing technology: hot rolling + annealing shot pickling + cold rolling + annealing pickling.

2D - a slightly shiny silvery white. Processing technology: hot rolling + annealing shot pickling + cold rolling + annealing pickling.

2B—Silver white and better gloss and flatness than 2D surfaces. Processing technology: hot rolling + annealing shot pickling + cold rolling + annealing pickling + quenching and rolling.

BA—The surface gloss is excellent and has a high reflectivity, like the mirror surface. Processing technology: hot rolling + annealing shot pickling + cold rolling + annealing pickling + surface polishing + temper rolling.

No.3—There is a good gloss and the surface is rough. Processing: Polishing and temper rolling for 2D or 2B with 100~120 abrasive (JIS R6002).

No.4—There is a good gloss and a fine grain on the surface. Processing: Polishing and temper rolling for 2D or 2B with 150~180 abrasive (JIS R6002).

HL - silvery gray with hairline stripes. Processing: Polishing the 2D or 2B with an appropriate size of abrasive material to continuously polish the surface.

MIRRO—mirror state. Processing: Grinding and polishing the 2D or 2B with the appropriate size of the abrasive material to the mirror effect.
