Stainless steel is also easier to keep clean and much more resistant to staining, corrosion and rust than chrome plating. Overall while chrome is less expensive and has a higher lustre finish, stainless steel is much more durable and will maintain it's finish for many years to come. Chrome plating Low friction Reduced weight Lesser expense Stainless steel Magnetic properties Weldability Hardness Durable These processes are constantly improving, so the differences between chrome steel and stainless steel may eventually vanish.

Sanitary stainless steel pipes also belong to the category of stainless steel pipes, but the requirements for sanitary steel pipes are more stringent than ordinary stainless steel pipes. First of all, the requirements for surface finish: the inner and outer surfaces of the steel pipe are polished so that the surface of the steel pipe is flat; that is, what we often call a mirror surface. The main purpose is to prevent the fluid material going in the tube from forming a wall in the tube, which will easily pollute and cause blockage in the tube after a long time. Secondly, the requirements for the passivation layer: After the polishing is completed, the steel pipe needs to be immersed in a passivation pool, and the surface of the steel pipe is oxidized with an acidic passivation solution to form a passivation layer to achieve the corrosion resistance of the steel pipe. In addition, there are certain requirements for the degree of oil prohibition: after the passivation is completed, carry out oil prohibition cleaning to remove the oil stains on the surface of the steel pipe. After completion, it needs to be checked with a grease analyzer. It is mainly to prevent the oil pollution of the pipe wall itself from contaminating the fluid substances in the pipe. The difference between sanitary stainless steel pipes and ordinary stainless steel pipes Compared with ordinary stainless steel pipes, the main difference of sanitary stainless steel pipes is that the inner surface is polished, which reduces resistance and increases fluidity when transporting fluids, making the fluids stainless and mixed. The debris on the pipe wall peeled off by the impact of the fluid also makes the inner wall of the steel pipe less prone to fouling and ensures hygiene.

304 stainless steel strip is a general purpose finished stainless steel material with stronger rust resistance than 200 series stainless steel materials. 304 stainless steel belt has excellent stainless corrosion resistance and good resistance to intergranular corrosion. To oxidizing acid, in the experiment is derived: concentration ≤ 65% of the boiling temperature below the nitric acid, 304 stainless steel belt has a strong resistance to corrosion. To the alkali solution and most of the organic and inorganic acids also have good corrosion resistance. 304 (18Cr-8N) stainless steel strip material: as a universal steel, has good corrosion resistance / heat resistance, low temperature strength and mechanical properties; stamping / bending and other hot workability, no heat treatment hardening phenomenon (non-magnetic, can be used to temperature Curtis -196 ° C ~ 800 ° C). Uses: Household products (1/2 class tableware/cabinets/interior plumbing/water heaters/boilers/bathtubs), automotive parts (windscreen wipers/mufflers/mouldings), medical appliances, building materials, chemicals, food industry, agriculture, marine parts.

The seamless and welded pipe manufacturing process   Welded pipes are manufactured using metallic sheets, with the wall thickness mentioned by the buyer. The length of the sheet prior to being welded is to be matched keeping both the inner and outer diameter of the pipe. These dimensions are to be given by the buyer during order placement. The welding method used, must be conducted in a manner that is set by the various standards.   The production of seamless pipes makes use of heat treatments. The alloy is first heated, followed by molding with the use of a solid billet. The solid billet is what guides the alloy into a component that is shaped in the form of a cylinder. Once the alloy forms cylinders, they are rolled such that they get stretched and form hollows. During this process, the hollowed center of the cylinder is irregular shaped. To get an even, hollow center, a bullet-shaped piercer point is thrust through the core of the billet, simultaneously, as the cylinder is rolled.   Seamless and welded pipe application   Since the main function of pipes is to ferry across materials, the application or the end-use of the product will be based on several factors including cost, strength, type of media being used in the application, the resistance of the alloy to corrosion in addition to the temperature and pressure requirements. Industries such as pharmaceutical, building & construction, food processing, beverage industry, nuclear & power generation, etc, make use of pipes to transport across their products. However, the industry that makes the most of these components is the petrochemical and natural gas industry.  

Stainless steel is the general name for a family of steels that are corrosion-resistant and contain a minimum of 10.5% chromium. The effect of this minimum level creates a chromium oxide layer on the surface, which is a self-healing oxygen barrier that stops further oxidation. Below 10.5% chromium, the oxide film is of insufficient durability to be self-healing. Stainless steels are widely used in most industries, including construction, marine, aerospace, automotive, and consumer goods. The material delivers high strength, durability, and resistance to corrosion, making it ideal for many cosmetic and open-environment components. Stainless steel is supplied in grades classed by their alloy content. The grade selected for an application depends on factors such as the environment in which it will be used, the required strength and durability, and the desired aesthetic standard. This article will define: What is stainless steel?, its composition, types, grades, properties, and applications. 1. Austenitic Stainless Steel Austenitic stainless steel is the most common classification, offering high corrosion resistance, ductility, and toughness. It is alloyed with a minimum of 16% chromium and 6% nickel, with other metals/non-metals such as manganese, nitrogen, and sometimes molybdenum. These steels can handle salt exposure, although some brown staining is possible. 2. Martensitic Stainless Steel This type of stainless steel is generally stronger and harder but suffers lower corrosion resistance. They contain 12–18% chromium and may also include nickel or molybdenum. 3. Ferritic Stainless Steel Ferritic stainless steels can have a broad range of chromium content (10.5–27%) and use higher carbon content steels than austenitic types. This group is less ductile and tougher, but still has good corrosion resistance and is often used for automotive applications. These steels react less well to salt and are not generally used in marine environments. 4. Duplex Stainless Steel Duplex stainless steels combine austenitic and ferritic stainless steels, with a carefully tuned proportion of both types of crystalline structure. They offer higher strength combined with great corrosion resistance and are often used in chemical processing and oil and gas applications.
