Defects in Welding and Prevent Methods
Briefly describe the defects that often occur in welding and their Prevent Methods Stoma The pores produced by the weld metal can be divided into internal pores, surface pores, and joint pores. (1) Internal pores: There are two shapes. One is that most of the spherical pores are produced in the middle of the weld. […]
Method of Preventing Defects in Cold Treatment of Die Steel
The essence of cold treatment is the continuation of quenching. The quenching stress at room temperature and the quenching stress at zero are superimposed, and when the stack response force exceeds the strength limit of the material, cold treatment cracks are formed. Die steel is mostly medium and high carbon alloy steel. After quenching, some of […]
What are the Uses of Stainless Steel Pump
1. Irrigation: farmland irrigation, sprinkler irrigation, drip irrigation. 2. Industrial pressurization: process water system, cleaning system, high-pressure flushing system, fire fighting system. 3. Water supply: water plant filtration and transportation, water plant district water supply, main pipe pressurization, and high-rise building pressurization. 4. Water treatment: ultrafiltration system, reverse osmosis system, distillation system, separator, and water […]
Don’t read this article, don’t buy stainless steel, the decoration water is too deep
Buy stainless steel Real blood and tears case: a low-quality stainless steel sink is used, although it is not rusty, it is similar to rustInferior quality stainless steel, the color will darken The sink has been used for two years, and the color now is very ugly, and it doesn’t shine even when I wipe […]
The influence of different elements on stainless steel
At present, there are more than 100 chemical elements known, and there are about 20 chemical elements that can be encountered in steel materials commonly used in industry. For the special steel series of stainless steel formed by people’s long-term struggle against corrosion, there are more than a dozen elements commonly used. In addition to the basic […]
Basic Knowledge of Nickel
Nickel is a chemical element with the symbol Ni and atomic number 28. Here is some Basic Knowledge of Nickel: Properties: Nickel is a silver-white metal with a slight golden tinge. It is malleable, ductile, and has a high melting point. It is ferromagnetic at room temperature and exhibits good corrosion resistance. Occurrence: Nickel is […]
For duplex stainless steel, how much do you know?
Duplex Stainless Steel (Duplex Stainless Steel, hereinafter referred to as DSS), refers to the ferrite and austenite content of each account for about 50% general is a youthful appearance also need to achieve at least 30% Stainless Steel. Duplex stainless steel is a collection of excellent corrosion resistance, high strength and easy processing, and many other […]
Cleaning of stainless steel surface damage and entrained foreign objects
Dust The production is often carried out in dusty venues. There are often many specks of dust in the air, which are constantly falling on the surface of the equipment. They can be removed with water or alkaline solution. However, the adhesion of dirt requires high-pressure water or steam to clean up. Floating iron powder […]
Why don’t you require stainless steel kitchen utensils and appliances can’t chrome?
Recently there are a lot of stainless steel products that can cause poisoning news release “chrome”, although experts have given you a detailed and clear explanation, there are still some people who remain skeptical. According to our country’s “national food safety standard stainless steel products” (GB9684-2011) regulation, chromium stainless steel products in the migration amount […]
