ASTM A268 TP430Ti Ferritic Martensitic Stainless Steel Seamless Tube For Heat Exchanger

430Ti stainless steel belongs to the ferritic stainless steel, which belongs to the 400 series stainless steel. High purity 430Ti (Nb) than ordinary 1Cr17 (430) stainless steel has better weldability, intercrystal corrosion resistance, better deep drawing property and excellent impact toughness and low brittle transition temperature uses, such as chemical plant absorption towers, heat exchangers, pipelines, containers, etc. Deep drawing equipment and components required to be welded in building interiors, kitchen equipment and household appliances.

430 stainless steel is a general steel with good corrosion resistance, better thermal conductivity than austenite, smaller thermal expansion coefficient than austenite, heat resistance fatigue, the addition of stabilizing element titanium, good mechanical properties of weld parts. 430 stainless steel is used for building decoration, fuel burner parts, household appliances, home appliance parts. 430F is a type of steel with easy cutting properties on 430 steel, mainly used in automatic lathes, bolts and nuts. 430LX adds Ti or Nb to 430 steel, reduces C content, improves processing performance and welding performance, mainly used in hot water tanks, heating water systems, sanitary appliances, household durable appliances, bicycle flywheels and so on.
Because of its chromium content, it is also called 18/0 or 18-0. Compared with 18/8 and 18/10, it contains slightly less chromium, and the hardness is correspondingly reduced.

ASTM A268 TP 410 Tubing Mechanical Properties

S43036 is a steel with good corrosion resistance and heat treatment properties. Its main components are chromium, iron, molybdenum, titanium and other elements, of which the content of chromium is 17%-19%, which is one of the main elements with excellent corrosion resistance. The material is generally used in the manufacture of special boilers, heat exchangers, chemical equipment, bearings and food processing equipment.
 

In terms of physical properties, S43036 has high strength, hardness and toughness. Its tensile strength is 550MPa, yield strength is 230MPa, and elongation is 35%. The hardness and strength of the steel can also be maintained at high temperatures, making it ideal for use in equipment operating at high temperatures.

In addition, the S43036 also has good processing performance. During cold working, the steel has good ductility and compression properties and can be easily processed into various shapes and sizes. At the same time, the steel is also suitable for hot processing, and better properties can be obtained through heat treatment and other methods.

In summary, the physical properties of S43036 show high strength, hardness, toughness and high temperature resistance, while having excellent corrosion resistance and processing properties. This makes it widely used in the manufacture of various industrial equipment and becomes an indispensable and important material.

As a stainless steel with strong corrosion resistance, 430Ti has been widely used in industrial applications. In order to achieve better performance and quality, the heat treatment of stainless steel is a very important link.

In the heat treatment process of 430Ti, it is first necessary to perform annealing treatment. The annealing temperature is 750℃~800℃, and the time is about 1 hour. In this process, rapid cooling method or air cooling method is needed to slow down the grain growth rate, so as to improve the ductility and plastic deformation ability of the material. At the same time, such a treatment can also improve the hardness and toughness of 430Ti, making it more tough and durable.

After the annealing treatment is completed, solid solution treatment is also required. The solution temperature is 980℃~1030℃, and the time is about 1 hour. This process is to dissolve chromium, titanium and other elements in 430Ti in steel chips to enhance the wear resistance and corrosion resistance of the material.

Finally, after the solution treatment is completed, 430Ti needs to be cooled. There are many ways of cooling treatment, such as water quenching or air cooling, the purpose is to allow the material to cool quickly, so as to form a more complete organizational structure in the lattice, and improve the corrosion resistance and strength of the material.

In short, the heat treatment process of 430Ti is crucial to improve its performance and quality. Only in the case of strict control of temperature and time and other parameters, can the 430Ti play its greater potential and application value.
