PRODUCTS DETAILS

Seamless square steel tubing, It is a hardened martensitic stainless steel alloy. Different from austenite grade It can be heat treated (" quenched and tempered ") to produce high strength and good ductility. When required strength, hardness and wear resistance and has a certain corrosion resistance Because of the hardening ability of this steel, other properties of this material and the resulting properties will be affected to a certain extent. The alloy can only be used effectively in mildly corrosive environments. Operating temperature range is limited a) excessive tempering at high temperatures results in loss of strength and b) loss of ductility at sub-zero temperatures Seamless square steel tubing, This steel is ideal for manufacturing high-stress parts in a variety of industries, including petrochemicals, automotive and power generation.

1. The plastic Plasticity refers to the ability of a metal material to produce plastic deformation (permanent deformation) without damage under load. 2. The hardness Hardness is a gauge of how hard or soft a metal material is. In this life in the production of hardness measurement method is the most commonly used in the indenter hardness method, it is to use a certain geometric shape of the indenter head under a certain load into the surface of the metal material to be tested, according to the degree of the indenter to determine the hardness value. Commonly used methods are Brinell hardness (HB), Rockwell hardness (HRA, HRB, HRC) and Vickers hardness (HV) and other methods. 3. The fatigue Strength, plasticity and hardness are indicators of the mechanical properties of metals under static load. In fact, many machine parts are operated under cyclic loads, and fatigue can occur under these conditions. The way also needs to have other section shape of special-shaped steel pipe. Low pressure fluid transport welded steel pipe (GB/T3092-1993) is also known as general welded pipe, commonly known as black pipe. It is a welded steel pipe used for conveying water, gas, air, oil, heating steam and other general lower pressure fluids and other purposes. The wall thickness of steel pipe is divided into ordinary steel pipe and thickened steel pipe. Pipe end form is divided into non - rebar steel tube (light tube) and with rebar steel tube. Steel tube specifications are indicated by nominal diameter (mm), which is an approximation of the inner diameter. It is customary to use inches, such as 11/2. The welded steel pipe used for low pressure fluid transportation is mainly used as the original pipe of galvanized welded steel pipe used for low pressure fluid transportation. Galvanized welded steel pipe for low pressure fluid transportation (GB/T3091-1993) is also known as galvanized electric welded steel pipe, commonly known as white pipe. It is a hot dip galvanized welded (furnace welding or electric welding) steel pipe used for conveying water, gas, air oil, heating steam, warm water and other general low pressure fluids or other purposes. The wall thickness of steel pipe is divided into ordinary galvanized steel pipe and thickened galvanized steel pipe. The end of the pipe is divided into galvanized steel pipe without thread and galvanized steel pipe with thread. Common carbon steel wire bushing (GB3640-88) is used to protect the wire in industrial and civil buildings, installation machinery and equipment and other electrical installation projects. Straight seam electric welded steel pipe (YB242-63) is a steel pipe with longitudinally parallel welds. Usually divided into metric welded steel pipe, welded thin-wall pipe, transformer cooling tubing and so on. Spiral seam submerged arc welded steel pipe (SY5036-83) for pressure fluid transportation is a spiral seam steel pipe, which is made of hot rolled steel strip as tube blank, often formed at warm temperature and welded by double-sided submerged arc welding method. The steel pipe has strong bearing capacity and good welding performance. It is safe and reliable to use after all kinds of strict scientific inspection and testing. Large diameter steel pipe, high transmission efficiency, and can save the investment of pipeline laying. Mainly used for conveying oil and natural gas pipelines. seamless square steel tubing Like most non-stainless steels, it can be hardened by "quenching and tempering" heat treatment. It contains at least 11.5% chromium, enough to provide corrosion resistance. When it Maximum corrosion resistance is achieved when hardened and tempered and then polished. Class 409 is a general purpose grade usually supplied in hardened but still workable form for applications requiring high strength and moderate heat and corrosion resistance.
