Factory source Erw Steel Pipe - High pressure boiler pipe Custom manufacturers – Lu
Introduction It is a kind of boiler tube and belongs to the category of seamless steel tubes. The manufacturing method is the same as that of seamless pipes, but there are strict requirements on the steel grades used in the manufacture of steel pipes. High-pressure boiler tubes are often in high-temperature and high-pressure conditions when used, and the tubes will be oxidized and corroded under the action of high-temperature flue gas and water vapor. The steel pipe is required to have high d... -

Introduction Tool steel is steel used to manufacture cutting tools, measuring tools, molds and wear-resistant tools. Tool steel has high hardness and can maintain high hardness and red hardness at high temperatures, as well as high wear resistance and appropriate toughness. Tool steel is generally divided into carbon tool steel, alloy tool steel and high-speed tool steel. High-speed tool steel is an alloy tool steel that contains C, Mn, Si, Cr, V, W, Mo, Co. And it can be used as a high-speed... -
China Manufacturer for Stainless Steel Industrial Pipe - Rectangle pipe Q195 Q235 Q345 Q215 Square and rectangular – Lu
Introduction A steel material that is open at both ends and has a hollow and concentric cross-section, The specifications of steel pipes are expressed by external dimensions (such as outer diameter or side length) and inner diameter and wall thickness. The size range is very wide, from small diameter capillary tubes to large round steel pipes with a diameter of several meters. Round steel pipes can be used for pipelines, thermal equipment, machinery industry, petroleum geological drilling, co... -
Professional China Low Alloy Plate - Bearing steel 9Cr18 G20CrMo GCr15High carbon chromium steel – Lu
Introduction Bearing steel is the steel used to make balls, rollers and bearing rings. Bearing steel has high and uniform hardness and wear resistance, and high elastic limit. The requirements for the uniformity of the chemical composition of the bearing steel, the content and distribution of non-metallic inclusions, and the distribution of carbides are very strict. It is one of the most stringent steel grades in all steel production. In 1976, the International Organization for Standardizatio... -
Free sample for Galvanized Flat Bar Steel - Galvanized steel strip Q235 Q195 SGCC Hot in the Chinese market – Lu
Introduction Galvanized steel strip is a raw material called (zinc, aluminum) that is cold-rolled or hot-rolled, long and narrow strip steel plate is plated to varying degrees with a layer of (zinc, aluminum). Hot-dip galvanizing has the advantages of uniform coating, strong adhesion and long service life. The hot-dip galvanized strip steel matrix undergoes a complex physical and chemical reaction with the molten plating solution to form a corrosion-resistant zinc-iron alloy layer with a comp... -

Hot-rolled stainless steel plate has relatively low strength and poor surface quality (oxidationlow finish), but good plasticity, generally medium-thickness plate, cold-rolled plate: high strengthhigh hardness, high surface finish, generally thin plate, can be used as Board for stamping. It is an alloy steel that is not easy to rust, but it is not absolutely r... -
Factory Price For Hot Rolled Stainless Steel Plate - Stainless steel seamless pipe/tube 201 304 304L 316 316L 310S – Lu
Introduction Stainless steel seamless steel pipe is a long steel with a hollow section and no joints on the periphery. It is a steel pipe resistant to corrosion by weak corrosive media such as air, steam, water and chemical corrosive media such as acid, alkali and salt. Also known as stainless acid-resistant steel pipe, the corrosion resistance depends on the alloying elements contained in the steel. Chromium is the basic element for the corrosion resistance of stainless steel. When the chrom... -
