Stainless steel pipe drilling?
Stainless steel itself is not high hardness, but it is difficult to processing reasons:Because the stainless steel contains C element is low, hardness is not high, and not easy to deformation, plasticity is poor, this is the iron and steel organization grain concentration caused by. This allows the drill to increase its viscosity when drilling, and it is not easy to chip out. The drill is easy to burn at this time. Through the practice comparison, we know that the opening of 135 degree bit is much easier when the control speed is 300-500 to /min. It is much easier than the drilling of 118 degree hole on the same material.
General requirements for processing stainless steel workpiece hole smooth, less burr, white technology generally choose high-quality grinding drill, on the market are mostly black rolling process, the main difference between full grinding and rolling process is drilling with the drill chuck supporting the overall use of small amplitude and hole grinding, less burr, the accuracy is high especially, when batch processing efficiency.
Acid resistant stainless steel is stainless steel, the resistance of air, steam, water and other weak corrosive medium or with stainless steel known as stainless steel; while the resistance to chemical corrosion (acid, alkali and salt chemical etching) corrosion of steel called acid resistant steel. Because of the difference in the chemical composition of the two, and make their corrosion resistance is different, ordinary stainless steel is generally not resistant to chemical medium corrosion, and acid resistant steel are generally stainless steel.
