qThe high surface hardness， wear resistance and leveling make the appearance of stainless steel pipe consistent with that of other nickel plated parts， and avoid the corrosion of contact potential difference between stainless steel pipe and other bright nickel. After using the bright nickel solution for a period of time， due to the accumulation of organic impurities caused by the decomposition products of the brightener and the pollution of some other metal impurities，Stainless steel round steel there is no turnover in the long-term sales of stainless steel plate，Price of stainless steel plate in 2015Ability to defend against radiation stainless steel belt and stainless steel pipe， so as to avoid the second-hand price difference， and the price is % higher than the market price! The price of more than one ton is higher! So that the nickel bath can not get the ideal bright nickel coating， it is necessary to carry out large-scale treatment. In the solution of bright nickel plating on stainless steel pipe， the brightener has developed rapidly and has many varieties. To sum up， the development of brighteners has experienced four generations. Instead of the original product， saccharin and butynediol can be plated with bright nickel with high flatness. Its application flourished in the s and s. It seems that due to the instability of butynediol in the nickel plating bath， short service life and rapid accumulation of organic impurities， the nickel bath needs to be treated frequently. Therefore the second generation nickel plating brightener，Stainless steel round steel such as b brightener is synthesized by branching epoxy chloropropyl or epoxy with butynediol. The situation is improved. Be and retain alkynyl， and then progress is made to polymerize pyridinyl， It has formed the third generation of products with faster light output speed， less amount of brightener and longer service life. Now it further uses various combinations of nickel plating brightener intermediates to form a new brightener， which has developed to the fourth generation of products. It has less usage， stainless steel pipes with deep plating capacity mainly include hot rolled hot extruded and cold drawn (rolled) stainless steel pipes. According to the difference of metallographic structure of stainless steel， it mainly includes semi Ferritic and semi martensitic stainless steel pipe， martensitic stainless steel pipe， austenitic stainless steel pipe， austenitic ferritic stainless steel pipe，Stainless steel round steel etc.

It will bring new changes in various fields.
YlThe heat-treated alloy should be DEG at low temperature; Annealing treatment at the temperature of F， then rapid cooling and water quenching. This treatment is applied to solid melt annealing and stress relief. Stress relief treatment， such as below DEG; F， which is easy to lead to the precipitation of harmful metal or non-metallic phases.
It is generally suitable for the welding of thin plates below mm， with the characteristics of beautiful weld formation and small welding deformation.
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 .mm， which is used to manufacture various power transformers，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 pulse transformers， magnetic amplifiers， converters and other iron cores with working frequency above Hz.
bThe 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 s， 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 tgftgftgftgf， 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.
ZBasic weight (density) / kg of steel plate: SPCC & mdash& 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.
HQuality AssuranceQuality: different steel strip materials determine the quality of stainless steel， which is a major factor affecting the price of stainless steel at present.
uNIf you want to choose a high-quality stainless steel pipe water supply pipe， you should first see whether its material is superior. Stainless steel is a material with strong corrosion resistance and high sanitation and cleanliness. Not only the outer wall is very beautiful， but also very smooth and smooth， and the incision is smooth. There will be obvious differences in material between the advantages and disadvantages of stainless steel pipe water supply pipe.
The folded stainless steel hot rolled strip is hot rolled into a strip with a thickness of mm-mm and a width of mm-mm.
Stainless steel with domestic (imported) stainless steel belt: stainless steel coil， stainless steel spring
production costswAccording 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.
Y. Domestic wce cerium tungsten electrode is used for electrode data. The shape and diameter of the end of cerium tungsten electrode have a great impact on the fluctuation of welding process and weld formation.
Oxygen plus gas flame can not cut stainless steel plate because stainless steel is not easy to be oxidized.

Rust is not stainless steel. There may be something wrong with the steel quality. & rdquo; in fact， this is a one-sided wrong view of the lack of understanding of stainless steel. Stainless steel will also rust under certain conditions
