SS304 Nipple Fitting

SST machinery can produce custom nipple fittings according to customers’ drawings with material SS303 SS304 SS316. Our SS304 nipple fitting can be all thread ends or barb ends or either of them.

The packaging of SS304 nipple fitting is standard export mass packaging, we will assemble thread cap to protect the female, and put them into one big plastic bag, then package the plastic bag into carton boxes, the outside package is the plywood pallet, which can afford long time sea delivery.

There are thousand kinds of stainless steel, among which the Austentic stainless steel and Martensitic stainless steel is very popular and widely used in daily life. 

Austenitic-ferritic duplex stainless steel

It has the advantages of both austenitic and ferritic stainless steels, and has superplasticity. Austenitic and ferritic structures each account for about half of stainless steel. In the case of low carbon content, the chromium (Cr) content is 18% to 28%, and the nickel (Ni) content is 3% to 10%. Some steels also contain alloying elements such as Mo, Cu, Si, Nb, Ti, and N. This type of steel has the characteristics of both austenitic and ferritic stainless steels. Compared with ferrite, it has higher plasticity and toughness, no room temperature brittleness, and significantly improved intergranular corrosion resistance and welding performance. The 475 ℃ brittleness and high thermal conductivity of element stainless steel have the characteristics of superplasticity. Compared with austenitic stainless steel, it has high strength and significantly improved resistance to intergranular corrosion and chloride stress corrosion. Duplex stainless steel has excellent pitting corrosion resistance and is also a nickel-saving stainless steel. 

Martensitic stainless steel

High strength, but poor plasticity and weldability. The commonly used grades of martensitic stainless steel are 1Cr13, 3Cr13, etc. Due to the high carbon content, it has high strength, hardness and wear resistance, but the corrosion resistance is slightly worse, and it is used for high mechanical properties and corrosion resistance. Some general parts are required, such as springs, turbine blades, hydraulic valves, etc. This type of steel is used after quenching and tempering. Annealing is required after forging and stamping.
