The steel grades for JIS mechanical structures are: S + carbon content + letter code (CK), in which the carbon content is represented by the intermediate value & times; 100, the letter C: represents carbon, and K: represents steel for carburizing. For example, the carbon content of carbon coil s20c is 0.18-0.23%. The grades of silicon steel sheets in China and Japan are.

%).It means: 100 times of Dr + iron loss value (iron loss value per unit weight when 50Hz repeated magnetization and sinusoidal magnetic induction intensity is 5T) + 100 times of thickness value. For example, dr510-50 indicates that the iron loss value is hot-rolled silicon steel plate with thickness of 0.5mm. The grade of hot rolled silicon steel sheet for household appliances is expressed by JDR + iron loss value + thickness value, such as jdr540-50.

.The back side is not protected by argon, and the flux coated welding wire (self protective flux cored welding wire) + TIG process is adopted. In the 1990s, the backing welding wire has been developed. Recently, China has also developed the stainless steel backing welding wire (i.e. flux coated welding wire, such as tgf30tgf308tgf30tgf347, etc.) It has been applied to the actual construction and achieved good results. We have successfully applied it in the capacity expansion and reconstruction project of Urumqi Petrochemical.

No matter under dynamic load or static load, it has higher energy absorption capacity than austenitic stainless steel, which has obvious advantages and practical application value for structural parts to deal with sudden accidents such as collision, duplex stainless steel has the following disadvantages: its universality and versatility are not as good as austenitic stainless steel. For example, 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 above conditions can cause corrosion of the protective film on the surface of stainless steel.

There are ba face, 2b face, (white skin), 2D face, (frosted), HL (wire drawing), 8K face and other surfaces with good quality and brightness.

This kind of steel pipe can be divided into stainless steel seamless steel pipe and stainless steel welded steel pipe (slotted pipe). According to different manufacturing processes, it can be divided into several basic types: hot rolling, cold drawing and cold rolling. According to the section shape it can be divided into circular pipe and special-shaped pipe. Circular steel pipe is widely used, but there are also some square, rectangular, semicircular hexagonal, equilateral triangle Octagonal and other special-shaped stainless steel pipes.

Deburring: after the pipe is cut off the burr shall be removed to avoid cutting the sealing ring.

Folding and editing this section of silicon steel strip grain oriented silicon steel strip, also known as cold rolled silicon steel strip for telecommunications industry, is a silicon steel strip with grain oriented structure and thickness less than 0.20mm, which is used to manufacture various power transformers,Round edge stainless steel strip, pulse transformers, magnetic amplifiers, economic sanitary and energy-saving water pipe, whether it is for household or large engineering buildings

The above conditions can cause corrosion of the protective film on the surface of stainless steel.

Fabrication of stainless steel pipe

OK or not?.Let PS be the external force at the yield point s and fo be the cross-sectional area of the sample, then the yield point & sigma; S = PS / fo (MPA),Stainless steel shower pipe, MPa is called MPa, equal to n (Newton) / mm (MPA = 106pa, PA: Pascal = n / M

Flux coated welding wire (self shielded welding wire) shall be used for backing TIG welding.

Cold rolled oriented silicon steel strip consists of nominal thickness (expanded by 100 times) + code G: ordinary material, P: high oriented material + guaranteed iron loss value (the value after expanding the iron loss value when the frequency is 50Hz and the large magnetic flux density is 7T by 100 times). For example,Stainless steel strip, 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, flashlight and other hardware.

.If packing is not required, it shall be indicated in the contract and will not bear the problem of scratching and scratching the surface of stainless steel pipe due to opening the packing bag.

The atoms around the gap rearrange with time, resulting in the continuous accumulation of holes, weakening the material, and finally forming macro cracks, high temperature promotes the accelerated oxidation of materials and the accelerated diffusion of atoms. Under the action of stress, the interaction between internal defects and dislocations can significantly reduce the low cycle fatigue performance of stainless steel tubes. The law of creep deformation of stainless steel pipe can be described by creep curve, which reflects the relationship between deformation and time under specific temperature and stress structure. The typical creep curve includes three stages: creep stage, with a gradually slowing creep rate; The second stage of creep: steady-state creep stage, which is an important stage when the stress process and recovery process reach equilibrium; In the third stage of creep, the creep process accelerates until fracture.

There are about 45 types of hot rolled (hot) stainless steel pipes with a diameter of 54-480mm and 36 types with a wall thickness of 5-45mm. There are 65 types of cold drawn (rolled) stainless steel pipes with a diameter of 6-200mm and 39 types with a wall thickness of 0.5-21mm.
