Duplex stainless steel is classified according to the level of PRE:

904L stainless steel (N08904, 14539 stainless steel ) super austenitic stainless steel containing 14.0-18.0% chromium, 24.0-26.0% nickel, 4.5% molybdenum.

According to the customer's request, we imported 500 kg hastelloy alloy 5.5mm material from Germany. The good have arrived at our factory.These raw materials are used to make a mustolloy wire mesh. Hastelloy material from Germany is more pure than China's. If it is used to make into wire mesh, the q

Chromium is the most basic alloying element in stainless steel, and its content is generally above 13%. Its main role is to improve the corrosion resistance of steel. In the oxidizing medium, there is a solid and dense chromium oxide on the surface of the steel to protect the steel. Chromium dissolved in steel can significantly increase the electrode potential of steel and reduce the electrochemical corrosion caused by different electrode potentials. Chromium can also be combined with nickel to form a single-phase austenite structure and impart good corrosion resistance, good toughness and strength to steel. It can be seen that the role of chromium in stainless steel is particularly important. In summary, the role of chromium in metallic materials is very important.We fully realize this, and reasonable use of chromium in various materials can improve the performance of materials.

Reasons of Stainless Steel RustThere may be several reasons for the rust of stainless steel materials:1,Chloride 2,Solution treatment 3,Intergranular 4,Surface markscorrosion

321 stainless steel is same with grade DIN1.4541 stainless steel .321 stainless steel is Ni-Cr-Mo stainless steel, and its performance is very similar to 304.But, due to the addition of titanium metal, it has better resistance to grain boundary corrosion and high temperature strength. The addition of titanium metal effectively controls the formation of chromium carbide

Thanks for carpenter 20 wire mesh of quotation from my French customerEmail :Konstantin.Vasilev@******.**Hello,I would like to request price specification for 600 m2 Carpenter 20 Wire Mesh. If you have delivery option to Finland I would like to get price for it as well.Thank you! Best regards,Konst

In stainless steel Chromium makes a decisive action.So ar all of the stainless steel contains chromium.

The hastelloy C276 is one kind of hastelloy alloy and it is Ni-Cr-Mo alloy.Ni is about 55%,Cr is 16% and Mo is 16%.Hastelloy alloy is suitable for oxidizing and reducing media chemical industry.It offers resistance to cloride corrsion becourse of higher molybdenum and chromium .Tungsten make the crr

The 254SMO wire mesh(DIN1.4547 or UNS S31254 wire mesh) is a highly corrosion-resistant stainless steel containing high chromium and high molybdenum.Even in harsh environments such as high temperature and sea water,254SMO maintains good corrosion resistance.
