If it is necessary to ensure non aging property， add n at the end of the brand as spcen. Quenching and tempering code of cold-rolled carbon steel sheet and strip: annealing status is a， standard quenching and tempering is s， / hard is / ， hard is / ， hard is . Surface processing code: dull finish rolling is D，304 stainless steel strip bright finish rolling is B. spcc-sd represents cold-rolled carbon sheet generally used for standard quenching and tempering and matt finish rolling. Another example is spcct-sb It refers to cold-rolled carbon sheet with standard quenching and tempering and bright processing and required to ensure mechanical properties.

— High strength cutting tool steel， slightly higher carbon content， after appropriate heat treatment
— It is easier to cut by adding a small amount of sulfur and phosphorus.

IDuring welding， the process of ventilation in advance and gas stop behind shall be adopted， and the adhesive cloth on the outside shall be torn off while welding. Because the blocking plate is composed of rubber and white iron sheet， it is not easy to be damaged， so this welding can well ensure that the inner side of the weld is filled with argon and its purity， so as to effectively ensure that the metal on the inner side of the weld is not oxidized and ensure the quality of weld backing welding.
Seamless stainless steel pipe， also known as stainless steel pipe， is made of steel ingot or solid pipe blank through perforation and then made by hot rolling， cold rolling or cold drawing. The specification of seamless steel pipe is expressed by outer diameter * wall thickness mm. With the implementation of Chinas reform and opening-up policy， and a large number of urban houses public buildings and tourism facilities have been built， people pay more and more attention to the problem of water quality， and the requirements are also increasing. Galvanized steel pipe， a common pipe， will gradually withdraw from the historical stage under the influence of relevant national policies because of its corrosiveness. Plastic pipe， composite pipe and copper pipe have become common pipes in the pipeline system. However， in many cases， stainless steel pipe has more advantages， especially the stainless steel pipe with wall thickness of only . ~ mm， which has the characteristics of safety， reliability， sanitation， environmental protection， economy and applicability in high-quality drinking water system， hot water system and water supply system that puts safety and sanitation first. It has been proved by engineering practice at home and abroad that it is one of the new， energy-saving and environmental protection pipes with good comprehensive performance of water supply system. It is also a very competitive water supply pipe， which will play an incomparable role in improving water quality and peoples living standards.

The effect of different stabilizers on the stability of ferritic stainless steel during pickling in base solution was studied by means of weight loss curve and scanning electron microscope. The results show that under the experimental conditions， both complex stabilizer HF and adsorption complex stabilizer -sulfosalicylic acid can completely remove the oxide layer on the surface of stainless steel The effect of adsorbing complex stabilizer -sulfosalicylic acid is obviously better than that of complex stabilizer HF in the stability effect and the flatness of the research results on the properties and microstructure of stainless steel surface s stainless steel pipe after pickling.
