Product Description
Stainless steel pipe is a kind of hollow long round steel widely used in industrial transmission pipelines and mechanical structural parts such as petroleum, chemical, medical, food, light industry, mechanical instruments, etc. In addition, when the bending and torsional strength is the same, the weight is relatively light, so it is also widely used to manufacture mechanical parts and engineering structures. It is also commonly used as furniture and kitchenware.
Stainless steel pipe is a kind of economical cross-section steel. It is an important product in the iron and steel industry. It can be widely used in life decoration and industry. Many people on the market use it to make stair railings, window guards, railings, furniture, etc.
System description: 304 stainless steel is the most widely used chromium-nickel stainless steel. As a widely used steel, it has good corrosion resistance, heat resistance, low-temperature, strength, and mechanical properties; Good thermal workabilities, such as stamping and bending, without heat treatment hardening (service temperature - 196 ºC - 800 ºC). It is resistant to corrosion in the atmosphere. If it is an industrial atmosphere or a heavily polluted area, it needs to be cleaned in time to avoid corrosion. Suitable for food processing, storage and transportation. It has good machinability and weldability. Plate heat exchangers, bellows, household products (category 1 and 2 tableware, cabinets, indoor pipelines, water heaters, boilers, bathtubs), auto parts (windshield wipers, mufflers, molded products), medical appliances, building materials, chemicals, food industry, agriculture, ship parts, etc. 304 stainless steel with strictly controlled content can also be called food-grade 304 stainless steel.
Product standard
For 304 stainless steel, the Ni element in its composition is very important, which directly determines the corrosion resistance and value of 304 stainless steel.
The most important elements in 304 are Ni and Cr, but they are not limited to these two elements. Specific requirements are specified by product standards. According to the common judgment in the industry, as long as the Ni content is greater than 8% and the Cr content is greater than 18%, it can be considered as 304 stainless steel. This is why this type of stainless steel is called 18/8 stainless steel in the industry. The relevant product standards have very clear provisions for 304, and these standards have some differences for different stainless steel shapes. Below are some common product standards and tests.
To determine whether a material is 304 stainless steel, it must meet the requirements of each element in the product standard. As long as one does not meet the requirements, it cannot be called 304 stainless steel.
