309S-manufacture,factory,supplier from China

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.

All steels have the same basic iron and carbon composition, but stainless steel also contains a healthy dose of chromium—the alloy that gives stainless steel its famous corrosion resistance.There are multiple grades called stainless steel, each with slightly different alloy composition, and therefore slightly different physical characteristics.Stainless steel must contain at least 10.5 percent chromium. Depending on the grade, it may contain much higher chromium levels, and additional alloying ingredients like molybdenum, nickel, titanium, aluminum, copper, nitrogen, phosphorous or selenium.

301 stainless steel strip is a sub-stable austenitic stainless steel with a fully austenitic organization under full solid solution conditions.The austenitic stainless steel has a fully austenitic organization under full solid solution conditions.In the austenitic stainless steel, 301 is Z easy cold deformation strengthening steel, through cold deformation processing can make the steel strength, hardness, and retain sufficient plastic, toughness, plus this steel has good rust resistance in atmospheric conditions, but stainless steel micro-wire in reducing media corrosion resistance is poor, in

Basic introduction about Duranickel  and Ni-Mo、Ni-Mo-Cr HastelloyDuranickel:The nickel content of these alloys exceeds 94%. The ultrahigh nickel alloy containing 4.75% manganese is resistant to vulcanization at high temperatures. If heat treatment is carried out, Duranickel 301 will become stronger, which will cause the submicroscopic particles of Ni 3 Al and Ti to precipitate in the whole matrix. This process is called precipitation hardening. Duranikel maintains excellent spring performance at temperatures up to 600 ° F.

Stainless steel is initially produced in slabs, which are then put through a conversion process using a Z mill, which converts the slab into coil prior to further rolling. These wide coils are typically made at around 1250mm (sometimes a little wider) and are known as 'mill edge coils'.These wide coils are further processed using a range of manufacturing techniques such as slitting, where the wide coil is slit into a multitude of strands; this is where much of the confusion around the terminology comes in.

Recently, the price of stainless steel 904L has fluctuated more frequently. Supported by many factors such as raw materials and inventory, the price center has basically maintained an upward movement. The demand release situation is good, and the overall social inventory shows a downward trend. The stainless steel market is still running at a high level, and the spot transaction volume has increased. The price of raw materials has risen, but the overall market is not as calm as in 2016-2017.
