Ocr25Ni20 stainless steel plate,
Hot rolled belt, stainless steel etching belt, stainless steel stretching belt, stainless steel polishing belt, stainless steel soft belt, stainless steel hard belt, stainless steel medium hard belt, stainless steel high temperature resistant belt etc.
Production process of hot rolled stainless steel strip / coil: 1. Pickling → 2. High temperature rolling → 3. Process → 4. Annealing → 5. Leveling → ⒍ fine cutting → ⒎ packaging → 8. Reach customers.
.Deburring: after the pipe is cut off, the burr shall be removed to avoid cutting the sealing ring.
1: stainless steel plate: it can be divided into cold-rolled plate and hot-rolled plate. Its surface has bright surface, fog surface and matte surface. It is commonly known as stainless steel plate, including 2B plate and Ba plate. In addition, 1m * 2m, 22m * 44m, 5m * 3M, 5m * 6m. If customer demand is large, we can cut them according to customer size. In addition, we can replace wire drawing plate, anti sliding plate and electroplating plate
.The national standard thickness of stainless steel pipe mainly depends on the thickness of raw materials and processing technology. The thickness of welded pipe is basically the same as that of raw materials. For seamless pipe, it is slightly thinner than that of raw materials. At present, the stainless steel pipe industry is dominated by large negative difference, mainly for the consideration of cost saving, 0 thickness. It provides all kinds of stainless steel plates, stainless steel coils, stainless steel belts, stainless steel pipes for individuals and enterprises all over the country for a long time, on-site settlement and honest operation. There are offices all over the country for long-term cooperation. Generally, 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, etc. Compared with austenitic stainless steel, duplex stainless steel has the following disadvantages: its universality and versatility are not as good as austenitic stainless steel. For example, its service temperature must be below 250 ℃.
The inner and outer surfaces of precision stainless steel pipe and thick wall pipe shall be free of cracks, folds, crazing, cracks, rolling folds, delamination, scabs and other defects, which need to be completely removed (unless they are specially used for machining) And after removing the stainless steel pipe wall, the wall thickness and outer diameter shall not exceed the negative deviation. As long as some minor surface defects that do not exceed the allowable negative deviation do not need to be removed.
Inspection: after crimping, check the crimping size with a special gauge.
Windproof and ventilation. Where there is wind, please take measures to block the net, and take appropriate ventilation measures indoors.
Workshop cost.After hot rolling,309S hot rolled stainless steel plate, it is subject to heat treatment and pickling treatment.
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.
Production and manufacturing can be divided into hot-rolled pipe cold-rolled pipe, cold drawn pipe, pipe, etc.
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 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.
Range.(VI) the growth rate of fixed asset investment in the iron and steel industry dropped significantly. From 2013 to June, the investment in fixed assets in the iron and steel industry was 303.5 billion yuan, a year-on-year increase of 3%, of which the investment in ferrous metal smelting and rolling was 235.6 billion yuan, a year-on-year increase of 3%, down 1 percentage point from the same period in 2012; The investment in ferrous metal mining and dressing was 67.9 billion yuan, and the growth rate fell sharply by 15 percentage points.
Stainless steel pipe factory stainless steel products are widely used in hardware products, furniture, mechanical structure mechanical accessories, precision medical instruments, fluid transmission pipelines, such as furniture, machinery, medical oil, natural gas, water, gas, steam and other industries.
Stainless steel water supply pipe is a healthy, economic, sanitary and energy-saving water pipe, whether it is for household or large engineering buildings
.Usage: widely used in automobile, tractor and other industries.
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, subways, household cars and so on!
