Stainless steel is a hard steel, which has corrosiveness and wear resistance properties. And because its hardness is large which makes the operation difficult, so that we must pay attention when cutting. 1. Use chrome-plated or nitrided saw blades. Chrome-plated saw blades are specially designed for the characteristics of stainless steel and are good for cutting stainless steel to avoid steel angle bar deformation. 2. The  stainless steel angle bar  cutting machine should choose the power ≥300 model. 3. A great temperature will be generated during cutting, and the choice of cutting fluid, cooling method, lubrication and cleaning also play a great role in cutting. Commonly used cutting fluids include mineral oil, vegetable oil, emulsion, etc. Choose the right cutting fluids according to different machine parts.

  1.       The mechanical method is to use the pressure, impact, shearing, grinding and other forces generated by various manual and power tools or different types of mechanical equipment to act on the castings to achieve the purpose of cleaning.  2.       The physical method is to use arc, plasma, laser, ultrasonic and shock waves to clean the castings.  　　 3.       The chemical method is to use hydrofluoric acid to dissolve silicon dioxide and salt solution electrolysis to remove the sticky sand of small and medium-sized castings; some metals are also oxidized and gas-cut by the characteristics of intense oxidation at high temperatures.   HCADTO Stainless Steel Co., Ltd.   the Stainless Steel Division of ADTO GROUP, specializes in manufacturing stainless steel pipes,  stainless steel angle bar , flat bar, round bar, square bar, hexagonal bar and channel bar in various grades and si...

Quality inspection of   stainless steel pipe ： 1. Tube Surface checking. Checking the surface of the stainless steel tube blank under the integrated light, and the estimated distance is 45±5 cm. 2. Pipe surface checking. Inspection according to the quality inspection standard of the polished surface of the stainless steel pipe. 3. The organic chemical composition testing of stainless steel plates is authorized to entrust an external testing center for testing. 4. The non-concentricity of the stainless steel pipe is accurately measured at three places of the stainless steel pipe diameter with the symmetry of a micrometer, which is indicated by the difference between the high value and the minimum value. 5. Diameter specifications, inner diameter specifications, and dimensions are accurately measured with a micrometer. The arc position is accurately measured with an R gauge, and the length specification is accurately measured with a meter ruler. The thickness of the stainless steel p...

1. Easy cleaning. It does not require metal cleaning agents and won't stick to fingerprints and dust, and has super fingerprint and anti-fouling effects. 2. The fingerprint-free transparent film layer can protect the metal surface from scratching easily, because the surface electroplating gold oil has good film properties and high hardness. 3. The appearance has strong texture with oily moisturizing, soft hand feeling, and retains a good metallic texture. Stainless steel plate  has excellent anti-rust performance without fingerprints. A protective film is formed on the surface of the metal to effectively prevent the outside from corroding the inside of the metal and increase the life of the product.

Stainless steel pipes  have different theoretical weights because of their different materials. The steel pipes with the same material, diameter, and thickness may have different weights due to the length error of the pipe and other reasons. Therefore, the weight of stainless steel pipes is a theoretical relative weight, and there is no steel pipe with absolutely the same weight. The calculation formula for the weight of stainless steel pipe is as follows: 304 round tube: (outer diameter-thickness) × thickness × density (0.02491) × length 304 square tube: [(side length×4)÷3.14－thickness]×thickness×density (0.02491)×length 304 rectangular tube: [(length + width)×2÷3.14－thickness]×thickness×density (0.02491)×length Density of 201 material (0.02491) Density of 316L material (0.02507) HCADTO Stainless Steel Co., Ltd.  the Stainless Steel Division of ADTO GROUP, specializes in manufacturing stainless steel pipes, stainless steel angle bar, flat bar, round bar, square bar, hexagonal...

For 304   stainless steel pipe , the greater the tensile strength, the smaller the elongation, so that it needs great bending strength and bending angle. If the yield strength of the 304 stainless steel tube is greater, the elastic recovery will be greater. How to quickly and easily bend stainless steel pipe? Here we will introduce you 2 methods:  1. Cold bending method: Generally, Use a bending machine to roll forming for many times, but if the camber is too small, it is prone to deformation, you should to take care of that. 2. Hot bending method: Filling 304 stainless steel pipe with sand, then bending in high temperature. This method is the much better than cold bending method, but it cost a lot which can not do mass production.

Stainless steel angle bar   is a long strip of steel whose two sides are perpendicular to each other. Stainless steel angle bar can be divided into equilateral stainless steel angle bar and unequal stainless steel angle bar. Stainless steel angle bar is a carbon structural steel for construction, mainly used for metal components and the frame of the factory building. The raw material billets for the production of stainless steel angles bar are low-carbon square billets. The finished stainless steel angle bar are delivered in a hot-rolled, normalized or hot-rolled state. Stainless steel angle bar can be classified according to their materials. They are martensitic stainless steel, ferritic stainless steel, duplex stainless steel, austenitic stainless steel, precipitation hardening stainless steel etc..
