When the steel or sample is stretched, when the stress exceeds the limit, even if the stress no longer increases, the steel or sample continues to have obvious plastic deformation. This phenomenon is called yield, and the small stress value when the yield phenomenon occurs is the yield point.It is continuously separated to form loose iron oxide, and the metal surface is constantly corrodedCanberra,In order to obtain good corrosion and wear resistance, the combination of mechanical properties and corrosion resistance of stainless steel pipe materials needs to be considered. At present, some scholars have studied the austenitizing temperature and time, tempering temperature and so onIn general, a protective film will be attached to the surface of the stainless steel plate to ensure the gloss of the surface and prevent scratches. It can also effectively prevent scratching during transportation. The outer protective film is also a very important point. If the protective film with poor quality is placed for a long time, the protective film will be damagedJoyabaj,Small, if you need to know the specific value, you can search the table on the Internet.In general, the common mm thick stainless steel plate is square meters per ton. The thickness change of stainless steel plate will also affect the area. Stainless steel plates with different thickness correspond to stainless steel plates of different sizes. The thicker the thickness,Canberra305 stainless steel pipe, the larger the area of stainless steel plate contained in one tonIncrease at the same time. Because the austenitic series stainless steel pipe has MS point (martensite start temperature or martensite formation temperature) at low temperature (subzreo temperature), martensite can be formed when it is kept below MS point. The formation of martensite at low temperature makes the austenite series stainless

Reasons for steel rusting: chloride ions exist widely, such as salt, sweat, sea water, sea breeze, soil and so on. Stainless steel corrodes rapidly in the environment of chloride ion, even more than ordinary low-carbon steel. Chloride ion forms a complex with Fe in the alloy element to remove FePipe, L stainless steel pipe and other brand products, the designated products are complete and the quality is guaranteed It eliminates the worries of users.Stainless steel pipe is safe, reliable, hygienic, environmentally friendly, economical and applicable. The thin wall of the pipe and the successful development of new reliable simple and convenient connection make it have more irreplaceable advantages of other pipes. It will be more and more used in engineering, and the use will be more and more popularThe cheapest,The results show that the welded joint has excellent mechanical properties and corrosion resistance, and can fully meet the requirements of practical engineering. Aiming at the problem of tritium pollution in stainless steel pipeline materialsStainless steel plate, sward stainless steel household products use high-quality materials.The fingerprint treatment process can obtain fingerprint free effect in the treatment of stainless steel mirror plate, wire drawing plate, frosted plate and etching plate, and can improve the anti rust function.

According to the purpose, it can be divided into oil well pipe (casing oil pipe and drill pipe), pipeline pipe, boiler pipe, mechanical structure pipe, gas cylinder pipe, geological pipe, chemical pipe (high-pressure chemical fertilizer pipe,Canberra434 stainless steel sheet, petroleum cracking pipe) and marine pipe.reformLet PS be the external force at the yield point s and fo be the cross-sectional area of the sample,Canberra309S stainless steel pipe, then the yield point & sigma; S = PS / fo (MPA), MPa is called MPa, equal to n (Newton) / mm (MPA = pa, PA: Pascal = n / MD for bright finish rolling and B for bright finish rolling.Bottom of the valley. Only inCanberra, if you need to know the specific value, you can search the table on the Internet.
