439 Stainless steel square steel
439 Stainless steel square steel 439 steel is to reduce the content of C on the basis of ordinary ferrite material (430), while adding Ti and other stabilizing elements, so that the resistance to intergranular corrosion, formability and weldability of the steel are improved. Compared with 304 steel, although the elongation is lower (about 30%), but the strength, corrosion resistance is equivalent, and corrosion resistance is better than 200 series materials.

Application:
Stainless steel profiles are often used in the construction of the project, this is because stainless steel has a good corrosion resistance, so the use of stainless steel production design products can be lasting to maintain the integrity of the sample, which is where the name of stainless steel comes from. Stainless steel containing chromium metal has good ductility, which is conducive to the processing and production of products, and can meet the needs of processors and design.
Stainless steel is very versatile, it can cover every corner of your life, bed frames, window bezels, cell phone cases, keys, spoons, railings and so on. And its wide range of uses is not only attributed to the performance of stainless steel, but also partly attributed to the diversity of stainless steel profiles. The types of stainless steel profiles are angles, flat bars and square bars.
The following are the specifications of stainless steel angles, flats and squares.
Stainless steel angles: Specifications Z10mmX10mm - Z150mmX150mm
The use of angle steel: widely used in building structure and engineering construction, such as: house beam, ship beam, industrial furnace, etc.
Stainless steel angle is a long strip of steel with two sides perpendicular to each other in an angle shape. There are equilateral stainless steel angles and unequal stainless steel angles. Equilateral stainless steel angle has two sides of equal width stainless steel flat steel, stainless steel square steel: specifications 10mmX10mm-750mmX750mm
Flat steel, square steel applications: used in industrial manufacturing, such as: household sinks, stainless steel valves, medical products, etc..
Stainless steel is widely used, in industrial facilities, experts expect the production of electrical appliances in the field of stainless steel consumption from 8% to 10%; in the water industry, as people increase awareness of environmental protection, thin-walled stainless steel water pipe safety and reliability, health and environmental protection advantages are increasingly concerned about: in the environmental protection Ding industry, Ding industry waste gas, waste and sewage outside the treatment facilities will be made of stainless steel, and the automotive industry is Stainless steel use of large-scale starting point.
It must be said that the birth of stainless steel to promote not only the industrial level of industry, but also to facilitate our lives. Stainless steel is just a big step forward in human history, but I believe that in the near future we can also invent a more practical metal material.
