310s/X8CrNi25-21/1.4841 Stainless Steel Pipe Fittings 2" SCH40s sandblast suface
"zheheng steel" produces and supply 310s/X8CrNi25-21/1.4841 Stainless Steel Pipe Fittings., Non-standard pipe fittings are also produced according to customer requirements. The company strictly implements ASTM B16.9 / B16.5,ASTM A403 SH3408, SH3409, DIN2605, EN10253, BS1965, JISB2312 and other standards for production.
310S (0Cr25Ni20) is an austenitic chromium-nickel stainless steel
with good oxidation resistance and corrosion resistance. Because of
the higher percentage of chromium and nickel, 310S has much better
creep strength and can continue to operate at high temperatures
High temperature resistance.

310S stainless steel is austenitic chromium nickel stainless steel,
which has good oxidation resistance and corrosion resistance of
310S stainless steel. Because a higher percentage of chromium and
nickel, it has much better creep strength and can continue to
operate at high temperatures. Good high temperature resistance. Due
to the high content of nickel (Ni) and chromium (Cr), it has good
oxidation resistance, corrosion resistance, acid and alkali
resistance, and high temperature resistance. The high temperature
resistant steel pipe is specially used for the manufacture of
electric furnace tubes, etc. After the content, due to its solid
solution strengthening effect, the strength is improved. The
chemical composition of austenitic stainless steel is based on
chromium and nickel. Elements such as molybdenum, tungsten, niobium
and titanium are added. Therefore, it has high strength and creep
strength at high temperature. Melting point is 1470 ℃, softening at
800 ℃, allowable stress continues to decrease.

Why choose us:
1. All pipe fittings are strictly implemented in accordance with
the standards, accept any third-party inspection, and return
service.
2. Before leaving the factory, 100% dimensional inspection, 100%
spectral test, mechanical and mechanical performance test,
pickling, pickling process are mainly aimed at the removal of
surface grease and harmful substances, complete surface passivation
to prevent oxidation. Some suppliers have not implemented ( Because
the surface is not visible to the naked eye after sandblasting)
annealing and solid solution (heat treatment), many goods on the
market are not heat-treated. When the pipe fittings are in some
cold or hot environments, the seam will slowly crack if it is not
heat-treated. This process is invisible to the naked eye, surface
sanding (many relatively inexpensive processes on the market),
bevel ends, etc.
3. Normally, the individual weight of our company's pipe fittings
is heavier than that on the market, (Ensure the back arc thickness)
to avoid the parts of the same wall thickness that cannot be seen
by the naked eye after the processing The pressure is guaranteed,
because many suppliers choose the material to the maximum limit in
order to minimize the cost.
RFQ:
1. Are you a trading company or a manufacturer?
Manufacturer and trading.
2. What are your main products?
All kinds of elbows, tees, caps, flanges, and steel pipes, etc with
different stainless steel,nickel alloy materials.
