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 […]
The difference between 304 and 30403
304 implementation of standards for: GB/T4237-2007,The equivalent of 304 l, 30403 executive standard: GB/T24511-2009, 30403 (00 cr19ni10 cr18ni10 (0))304 (0 cr18ni9 (06 cr19ni10)) The carbon content is low, generally recommended for pressure vessels. Stainless steel pressure vessel standards. Number: GB 24511-2009 The standard name: pressure equipment with stainless steel plate and steel strip Standard: current English […]
The main factors influencing the 304 stainless steel plate surface roughness
304 stainless steel manufactured by cold rolling, heat treatment, pickling, then through rough roller leveling, called a 2 d surface processing, 2 d can be pickling surface, can also be a rough surface. Again after pickling with large diameter and high precision polishing roll small reduction of flat (this only a small amount of lower […]
How to distinguish between stainless steel and stainless iron
The main elements of stainless steel are iron, chromium, and nickel. We usually divide stainless steel into nickel-chromium stainless steel and chromium stainless steel. The so-called “stainless iron” actually does not exist. “Stainless iron” is just an irregular name in stainless steel, which is a very unscientific verbal name. All alloy products of iron elements […]
Potion or spectrum, which is more reliable for detecting stainless steel?
202 and 304, the price difference between the two is nearly 1,000 yuan, one contains less than 4 nickels, and the other contains 8 nickels. It is difficult to distinguish with the naked eye. However, after dropping a little potion, 304 will hardly change color. And different materials, the color of the potion is also […]
Where is the advantage of cold-formed stainless steel plate?
From the perspective of consumption, China’s apparent consumption has reached the world’s highest level and is close to 1/4 of global consumption. Per capita consumption of stainless steel has reached 3.4KG, which has leaped to the forefront of developing countries, but the growth rate of consumption has gradually slowed down. From a rapid development stage […]
The origin of the ss plate number and identification method
1. Use international chemical element symbols and national symbols to represent chemical components, and Arabic letters to represent component content: such as China, Russia 12CrNi3A. 2. Use fixed-digit numbers to represent steel series or numbers; such as the United States, Japan, 300 series, 400 series, 200 series; 3. Use the Latin alphabet and sequence to […]
Features and advantages of the spinning process for ss pipe fittings
With the development of spinning technology, the spinning process gradually replaces the traditional process to produce ss pipe fittings. Western developed countries have imposed a technological blockade on my country regarding this technology. Therefore, our research goal is to achieve the ultimate thinning and spinning of ss pipe fittings and increase the diameter of stainless steel pipe […]
The Difference Between Stainless Steel Hardness HB, HR, HV
Introduction to Hardness: Hardness refers to the ability of a material to resist the pressing of hard objects into its surface. It is one of the important performance indicators of metal materials. Generally, the higher the hardness, the better the wear resistance. Commonly used hardness indicators are Brinell hardness, Rockwell hardness, and Vickers hardness. 1. […]
