SPHESPHE—& mdash; Hot rolled steel plate and strip for deep drawing.
4The pipes for pipe cutting shall be professionally cut by stainless steel. Rotate it for two circles， then slightly tighten the piece， and then rotate it for two circles until it is cut off. It must not be enough to allow personal strength to be in place at one time to lock the piece to cut off the pipe otherwise the pipe end will be cut off， and the pipe fittings or rubber rings cannot be inserted; After the pipe above DN is cut， the internal and external burrs must be removed with a hand grinder， and an appropriate outer slope opening shall be opened at the same time to avoid damaging the sealing ring.
lTherefore，Stainless steel coil the field with high utilization rate of stainless steel with high competitiveness and comprehensive quality will also be an important part of the sales plan.
Stainless steel has the ability of atmospheric oxidation，Price of stainless steel 304 seamless steel pipeOperation specifications for various that is， it also has the ability of corrosion resistance in the medium containing acid， alkali and salt， that is， corrosion resistance. However， its corrosion resistance changes with its own chemical composition， mutual state， service conditions and environmental medium type. For example， has absolutely excellent corrosion resistance in dry and clean atmosphere，Stainless steel coil but it is moved to In coastal areas， in the sea fog with a lot of salt， it will soon rust， while stainless steel performs well. Therefore， not any kind of stainless steel can resist corrosion and rust at any time
UDalahu series & mdash; Ferritic and martensitic stainless steel.
KqAccording to the production mode， stainless steel pipe is mainly divided into seamless pipe and welded pipe. Seamless steel pipe can be divided into hot-rolled pipe cold-rolled pipe， cold drawn pipe and extruded pipe. Cold drawing and cold rolling are the secondary processing of steel pipe; Welded pipe is divided into straight seam welded pipe and spiral welded pipe.
Mold cost: specifications are commonly used but not commonly used. Common specifications are rapid turnover and low mold sharing cost. Because of low utilization rate and high cost sharing， it is a special product manufacturing enterprise integrating R & D sales and service. It has long been specialized in selling L stainless steel pipe， the specification of a group of slightly larger formed pipes used in the production of pipe molds is about -.
Delivery status: to be delivered after heat treatment and leveling.
aThe recrystallization temperature changes with the shape variable. When the shape variable is %， the recrystallization temperature drops to ℃，Stainless steel coil and the recrystallization annealing temperature of cold deformed austenitic stainless steel is ~ ℃. At ℃， it needs to be kept warm for h，Price of stainless steel 304 seamless steel pipeOperation specifications for various fully burned at ℃， and then water-cooled.

YProduction departmentThe length of tungsten electrode protruding from the gas nozzle is preferably ~ mm. In places with poor shielding such as fillet welding， it is ~ mm， and in places with deep groove， it is ~ mm. The distance from the nozzle to the working is generally no more than mm.
xJPolishing at present， stainless steel products are generally polished in the production process， and only a few products such as water heater and water dispenser lining do not need polishing. Therefore， this requires good polishing performance of raw materials. The main factors affecting the polishing performance are as follows: . Surface defects of raw materials. Such as scratch，tisco stainless steel sheet,taigang stainless steel sheet,stainless steel sheet,stainless steel coil,stainless steel strip,stainless steel tube-TISCO Stainless Steel Co.,Ltd pitting， soaking， etc.
Stainless steel pipe will rust? Stainless steel pipe is a food grade stainless steel pipe recognized by the state. It is not absolutely non rusting， but it is not easy to rust compared with other steel grades. Many people will think that the stainless steel pipe is not rusty， especially the stainless steel pipe has high nickel content， which is more difficult to rust. If it is rusty， they will doubt whether it is fake， whether it will be replaced by stainless steel pipe， or there is a problem with the raw materials of the steel strip. In fact， these questions and judgments are one-sided views on the lack of understanding of stainless steel pipes. Stainless steel pipes may also produce rust and rust spots under certain conditions.
SPCCSPCC—& mdash; Cold rolled carbon steel sheet and strip are generally used， which is equivalent to qa. The third letter C is the abbreviation of cold. When it is necessary to ensure the tensile test， add t at the end of the brand as spcct.
Process inspectionlStainless steel belt， stainless steel packing belt， stainless steel belt， ultra-thin stainless steel belt.
YWhen installing and welding the fixed port of stainless steel pipe， it is difficult to vent on the inner side， and some sides are easy to be blocked. In this case， water-soluble paper + blocking plate can be used for blocking. That is， the easy to vent and good side can be blocked with blocking plate， the difficult to vent and bad blocking plate side can be blocked with water-soluble paper， and the weld on the outer side can be blocked with adhesive tape (see Table ) .
— The corrosion resistance is the same， and the strength is better because the carbon content is relatively high.
iJapanese cold rolled non oriented silicon steel strip consists of nominal thickness (expanded by times) + code a + iron loss guarantee value (the value after expanding the iron loss value when the frequency is Hz and the large magnetic flux density is T by times). Provide various brand products such as stainless steel plate， stainless steel coil， stainless steel belt and stainless steel pipe for a long time. The products of designated dealers are complete and the quality is guaranteed. For example， a means that the thickness is .mm and the iron loss guarantee value is ≤ cold rolled non oriented silicon steel strip.
cNIt 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.
Its alloy composition (chromium nickel， titanium， silicon， aluminum， etc.) and the internal structure of stainless steel coil plate are mainly composed of chromium. Chromium has high chemical stability， can form a passive film on the steel surface， isolate the metal from the outside， protect the steel plate from oxidation and increase the corrosion resistance of the steel plate. After the passivation film is destroyed， the corrosion resistance decreases.
