Stainless stee
Stainless steeThe cold working process performance and cold forming performance are much better than that of ferritic stainless steel.
Stainless steel water supply pipe is a healthy,Stainless steel pipe, economic, sanitary and energy-saving water pipe, whether it is for household or large engineering buildings
.Because stainless steel has many ideal properties required by building materials, and its development continues. In order to make stainless steel more neutral in traditional applications, existing types have been improved, and new stainless steel is being developed to meet the strict requirements of advanced architectural applications. Due to the continuous improvement of production efficiency and quality, stainless steel has become one of the cost-effective materials selected by architects. Stainless steel integrates performance, appearance and use characteristics, so stainless steel will still be one of the best building materials in the world.
410— Martensite (high strength chromium steel), good wear resistance and poor corrosion resistance.
.Both ends of the steel pipe shall be cut into right angles and burrs shall be removed.
Physical properties the total heat transfer coefficient of metal depends not only on the thermal conductivity of metal, but also on other factors. In most cases, the heat dissipation coefficient of film, rust scale and the surface condition of metal. Stainless steel can keep the surface clean, so its heat transfer is better than other metals with higher thermal conductivity. Liaocheng Suntory stainless steel provides the technical standard of stainless steel plate Stainless steel plate high-strength stainless steel plate with excellent corrosion resistance, bending workability, toughness of welding parts and stamping workability of welding parts. Specifically, Si, Mn, P, s, Al and Ni with an appropriate content of less than 0.02% of C, less than 0.02% of N more than 11% of Cr and less than 17% shall meet 12 & le; Cr Mo 5Si & le; 11 & le; Ni 30 (c n) 0.5 (Mn Cu) & le; Cr 0.5 (Ni Cu) 3Mo & Ge; 0, n & le; 0.030 stainless steel plate is heated to 850 ~ 1250 ℃ 0.006 & le; C, and then cooled at a cooling rate of more than 1 ℃ / S. in this way, it can become a high-strength stainless steel plate with martensite content of more than 12%, high strength of more than 730mpa, corrosion resistance and bending processability, and excellent toughness of welding heat affected zone. It can be significantly improved by reusing Mo, B, etc High stamping performance of welded parts.
After the installation of stainless steel water pipe cleaning pipeline, it is recommended to use 3% potassium permanganate for disinfection. It is strictly prohibited to use bleaching water for disinfection,Stainless steel cutting pipe, and clean it with clean water after disinfection. If it is not put into use for a short time, compressed air must be used to blow out the residual water in the pipe, so as to prevent the corrosion reaction between oxygen free in the pipe and other media.
Mechanical properties when the steel or sample is stretched when the stress exceeds the limit, even if the stress is no longer increased, the steel or sample continues to have obvious plastic deformation, and the small stress value when the yield phenomenon occurs is the yield point.
Hardness stainless steel pipes are usually measured by Brinell, Rockwell and Vickers hardness indexes.
Selection process of stainless steel pipe water supply pipe.
Click to view.Polishing 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: 1. Surface defects of raw materials. Such as scratch, pitting, soaking, etc.
Batch size: a small number of single batch products will affect the unit price.
309— It has better temperature resistance.
From the perspective of metallography, because stainless steel contains chromium, a very thin chromium film is formed on the surface, which is separated from the corrosion resistance of oxygen invaded in the steel.
Manufacturing cost.. 18%), s is the abbreviation of steel, P is the abbreviation of plate, h is the abbreviation of hot heat,201 stainless steel pipe, and C is the abbreviation of commercial. It generally represents hot-rolled steel plate and strip.
.Under plasma arc cutting corrosion conditions, there are dust containing other metal elements or attachments of dissimilar metal particles on the surface of stainless steel. In the air the condensate between the attachments and stainless steel connects them into a micro battery, which causes electrochemical reaction and the protective film is affected, which is called electrochemical corrosion.
Carbon structure delivery status: delivered in heat treatment (annealing, normalizing, tempering after normalizing, high temperature tempering).
