304ti stainlesIt is a kind of product manufacturing enterprise. It has long been specialized in L stainless steel pipe, s stainless steel pipe and 904L stainless steel pipe. Therefore,SUS302 stainless steel belt, the specification of a group of slightly larger formed pipes used in the production of pipe molds is about 6000-20000.
The process of this product determines its limited performance. Generally, the precision of seamless steel pipe is low: uneven wall thickness, low brightness on the inner and outer surface of the pipe, high sizing cost, which are not easy to remove; its detection and shaping must be processed offline. Therefore, it embodies its advantages in high pressure, high strength and mechanical structure materials.
.The shape of pipe end stainless steel pipe can be divided into smooth pipe and threaded pipe (threaded steel pipe) according to the state of pipe end. Threading pipe can also be divided into ordinary threading pipe (pipe for conveying low pressure such as water and gas, which is connected by ordinary cylindrical or conical pipe thread) and special threaded pipe (pipe for petroleum and geological drilling, which is connected by special thread for important threading pipe). For some special pipes, in order to make up for the impact of thread on the strength of pipe end the pipe end is usually thickened before threading (inner thickening, outer thickening or inner and outer thickening).
During butt backing, in order to prevent the back of the underlying weld bead from being oxidized, the back also needs to be protected by gas.
.It has good local corrosion resistance. Compared with austenitic stainless steel with the same alloy content, its wear-resistant corrosion and fatigue corrosion properties are better than austenitic stainless steel.
The Chinese brand of stainless steel plate is 0cr18ni12mo3ti (0Cr18Ni12Mo2Ti with paper should also be this brand). The new brand is 06cr17ni12mo2ti stainless steel plate. The stainless steel plate is added with Ti in SUS316 steel to improve the intergranular corrosion resistance. It is applied to the equipment of phosphoric acid,201 stainless steel embossed plate, acetic acid and acetic acid.
Good corrosion resistance suitable for a variety of media; The addition of Mo improves the corrosion resistance to reducing salts; It is resistant to marine and industrial atmospheric erosion, and can be used in seawater equipment; Due to its low carbon content, it has excellent grain boundary corrosion resistance; It can be used in pulp and paper machinery; Good processability and weldability.
The selection of stainless steel plate shall consider the operating conditions, such as manual operation or automatic operation, the performance and type of hot press, and the quality requirements for materials, such as hardness, gloss, etc. Economic accounting should also be considered. Each time the steel plate is newly polished, it is required to produce a number of decorative plates with slow quality.
Model 409 & mdash; Cheap model (British and American), usually used as automobile exhaust pipe, is ferritic stainless steel (chromium steel).
There are 45 kinds of hot rolled (hot) steel pipes with a diameter of 54 ~ 480mm,Price of 321 stainless steel strip, 36 kinds of wall thickness of 5 ~ 45mm, 65 kinds of cold drawn (rolled) steel pipes with a diameter of 6 ~ 200mm and 39 kinds of wall thickness of 0.5 ~ 21mm.
quality standard.Stainless steel pipe is a common material in stainless steel, with a density of 93 GCM, which is also called 188 stainless steel in the industry. High temperature resistance of 800 ℃, with the characteristics of good processing performance and high toughness, it is widely used in industry, furniture decoration industry and food and medical industry.
3 after deep drawing, small black spots and RI high imitation dging will also appear on the surface of the area with large deformation, which will affect the BQ attribute.
Standard provisions.
Cold rolled oriented silicon steel strip consists of nominal thickness (expanded by 100 times) + code G: ordinary material, 30g130 indicates that the thickness is 0.3mm and the guaranteed value of iron loss is ≤ 3 cold rolled oriented silicon steel strip. Liaocheng Suntory stainless steel provides electroplated tin plate and hot-dip galvanized plate: electroplated tin plate, electroplated tin sheet and steel strip, also known as tinplate. The surface of the steel plate (belt) is plated with tin, which has good corrosion resistance. In addition, it can be used as packaging material for cans, inner and outer sheath of cables, instrument and telecommunication parts, select appropriate maintenance slag; During continuous casting, the vibration marks formed on the surface of continuous casting slab due to the vibration of mold shall be; Electromagnetic stirring must be used in continuous casting of ferritic stainless steel pipe fittings.
According to the steel structure, austenite ferrite ferrite martensite and precipitation hardening note: precipitation hardening (precipitation strengthening): refers to a heat treatment process in which the metal is hardened by the segregation zone of solute atoms in supersaturated solid solution and / or the desolved particles are dispersed in the matrix. For example, austenitic precipitated stainless steel can obtain high strength by precipitation hardening at 400 ~ 500 ℃ or 700 ~ 800 ℃ after solution treatment or cold working. That is, the supersaturated solid solution of some alloys is placed at room temperature or heated to more & amp; gt;& amp; gt;
.High pressure water jet cutting (professional water cutting: Shanghai Xinwei)
The design shall be carried out according to the soil, water, grooved section, load conditions and other factors of the trench, which shall be firm and reliable to prevent collapse and support, and shall not hinder the pipe laying and pipe stabilization.
The application of stainless steel pipe in the automobile industry is developing rapidly. In recent ten years, stainless steel pipe materials have been widely used in public transportation tools such as buses, high-speed railway vehicles, household cars and so on!
