A179 Purpose: It is applicable to steel pipes for tubular heat exchangers, condensers and similar heat transfer equipment. The chemical composition of the steel is as follows: Carbon: 0.06%~0.18%, Manganese: 0.27%~0.63%, Phosphorus: 0.035%, Sulfur: MAX 0.035%.
Application: It is suitable for stress and pressure parts, as well as steam, water, gas and air pipelines for general purposes. A53 pipeline pipe belongs to American petroleum standard pipeline pipe. Pipeline pipe is used to transport oil, steam and water pumped out of the ground to oil and natural gas industrial enterprises through pipeline pipe. Pipeline pipe includes seamless pipe and welded steel pipe, with flat end, threaded end and socket end at the pipe end; The connection methods are end welding, coupling connection, socket connection, etc.
A106 GrB strength grade 415MPa. ASTM A106Gr. B seamless steel pipe is a kind of low carbon steel widely used in petroleum, chemical and boiler industries. The material has good mechanical properties. Seamless steel pipe for high-temperature operation ASTM A106 GR. B, steel grade: SA106B, Specification: 1/4 ″ - 28 ″, 13.7-711.2mm Steel grade: GRAD B, Standard: ASTM A106 - American Society for Testing and Materials.
X42 pipeline pipe is the pipeline pipe with steel grade of X42. The pipeline pipe is used to transport the oil, steam and water pumped out of the ground to the oil and natural gas industrial enterprises through the pipeline pipe. Pipeline pipe includes seamless pipe and welded steel pipe, with flat end, threaded end and socket end at the pipe end; The connection methods are welding, coupling connection, socket connection, etc.
Main application: used for making oil and natural gas transmission pipelines. API 5L generally refers to pipeline steel plate -- API 5L pipeline steel plate. When the pipeline steel plate is processed into large-diameter pipeline steel pipe, the oil, steam and water pumped out of the ground are transported to the oil and natural gas industrial enterprises through pipeline pipes.
DC01-A: Defects that do not affect the formability or surface coating are allowed, such as air holes, slight dents, small marks, slight scratches and slight coloring. DC01-B: The better surface shall be free of defects that may affect the uniform appearance of high-quality paint or electrolytic coating. The other surface shall meet at least surface quality A. The main application fields of DC01 materials include: automobile industry, construction industry, electronic equipment and household appliances industry, decorative purposes, canned food, etc.
S235JR is a European standard non alloy structural steel, which is equivalent to the national standard Q235B, that is, carbon structural steel with low carbon content. It is widely used for welding, bolting and riveting structures. It can also be used for building, bridge, ship, vehicle structural parts, manufacturing various tools, cutting tools, molds and measuring tools.
Due to moderate carbon content and good comprehensive properties, the strength, plasticity, welding and other properties are well matched, which is the most widely used. SS400 steel plate is applicable to bridges, ships and vehicles.SS400 is often rolled into wire rod or round steel, square steel, flat steel, angle steel, I-beam, channel steel, window frame steel and other section steel, medium thick steel plate. It is widely used in buildings and engineering structures. It is used for making steel bars or building workshop frames, high-voltage transmission towers, bridges, vehicles, boilers, containers, ships, etc., and is also widely used as mechanical parts with low performance requirements; C. Grade D steel can also be used as some professional steel.
[Main use of SPHC material] Hot rolled steel plate products are widely used in shipbuilding, automobile, bridge, construction, machinery, pressure vessel and other manufacturing industries due to their high strength, good toughness, easy processing and good weldability. With the maturity of new control technologies such as hot rolling dimensional accuracy, shape and surface quality and the continuous emergence of new products, hot rolled steel plates and strips have been more and more widely used and become more and more competitive in the market.
A36 is an American standard carbon structural plate, which is subject to ASTM A36/A36M. This standard is applicable to riveting, bolting and welding structures for bridges and buildings, as well as general purpose structural steel quality carbon steel sections, plates and bars.
Performance and application of material ST37: the material has good performance, that is, through cold rolling, it can obtain cold rolled strip and steel plate with thinner thickness and higher precision, with high straightness, high surface finish, clean and bright surface of cold rolled plate in Taiwan Strait, easy to be coated, various varieties, wide application, high stamping performance, non aging, and low yield point.
1020 belongs to high-quality carbon structural steel. Its strength is slightly higher than 1015 steel. It has good toughness, plasticity and weldability. It is rarely quenched and has no temper brittleness. Parts with high cold deformation plasticity, generally used for bending, calendering, edge bending and hammer arch processing, good welding performance of electric arc welding and contact welding, small thickness during gas welding, strict shape requirements or complex shapes are prone to cracks. Machinability cold drawing or normalizing state is better than annealing state, and is often used to manufacture various mechanical parts with low stress and high toughness requirements.
