Stainless Steel 904L Pipe & Tube Supplier in China-manufacture,factory,supplier from China

Super Austenitic 904L stainless steel tubes are designed for corrosive environments. By optimizing chemical composition, super austenitic 904L stainless steel tube is a super austenitic stainless steel with low C content and high alloying. 904L super austenitic stainless steel tube blank was successfully developed by specific production process.

904L (N08904,14539) super austenitic stainless steel contains 24.0-26.0% nickel, 4.5% molybdenum. 904L super austenitic stainless steel is a low carbon, high nickel, molybdenum austenitic stainless steel, which is a special material introduced from H·S Company in France. It has good activation-passivation transformation ability and excellent corrosion resistance. It has good corrosion resistance in non-oxidizing acids such as sulfuric acid, acetic acid, formic acid and phosphoric acid.

Both are good steels for high temperature and corrosion resistance, but the 904L stainless steel pipe is much better. See the following for details:310S stainless steel pipe main composition: 25Cr-20Ni-0.08CCountry code: 0Cr25Ni20 or 0Cr25Ni20Si2310S stainless steel pipe designed for high temperature environment, oxidation resistance is better than 309S steel, used as heat resistant steel and boiler.

904L stainless steel plate is widely used and has good corrosion resistance, heat resistance, low temperature strength and mechanical properties; good hot workability such as stamping and bending, no heat treatment hardening phenomenon. Widely used in household items (1, 2 tableware), cabinets, indoor pipelines, water heaters, boilers, bathtubs, auto parts, medical equipment, building materials, chemicals, food industry, agriculture, ship parts.The 904L pattern stainless steel plate has added anti-slip function on the basis of the original performance.

Laying points of stainless steel elbow in pipeline:1. In order to reduce the heat loss of the stainless steel elbow and prevent thermal deformation, the buried depth of the pipeline should be greater than 1.2 meters. (calculated from the top of the pipe). The burial depth in alpine regions should be appropriately deepened. At the same time, all pipes should be avoided to be laid below the water table.2. For areas where the groundwater level is high or it is difficult to dig deep for other reasons, measures should be taken as far as possible to avoid water insulators before burying the pipes.

Seawater corrosion resistant materials, and widely used in Marine engineering. However, in practical engineering application, the stainless steel connection, especially the welding area, often appears various corrosion damage, resulting in a great loss. Therefore, in this paper, according to the characteristics of seawater corrosion of stainless steel, the seawater corrosion and anticorrosion mechanism of its weld site were comprehensively analyzed and studied.

It’s important for those in the metal and steel worlds to recognize that even some products named similarly will be different in their detailed characteristics, and a good example here is welded metal tube versus seamless tube. Both forms of metal tube, these formats are actually very different and will have varying common applications for their use. we’re proud to offer several options when it comes to steel tube for any project, whether a bulk order or a smaller one, from manufacturing through processing and several other needs.

The oxide film on the surface of stainless steel square tube is thin and dense, which is not easy to fall off. Mechanical cleaning is a common and effective means of stainless steel surface treatment. The iron oxide scale cleaning machine is mainly composed of steel brush roller, driving device, high-pressure water system, cooling water system and clamping device.Some preparations need to be done before welding of stainless steel square tube, which can improve the quality and efficiency of tubeline welding and the safety measures of welding workers.
