23-12-2014· In the stainless steel making process lime is used in the AOD (argon oxygen decarburization ) process. High calcium and dolomitic lime used in BOF and EAF as well as in secondary refining must meet exacting physical and chemical properties. Typical specification of lime used in steel making is given in Tab 1.
Sintered powder filter discs; The stainless steel wire mesh filter disc is the most popular among the available varieties. It is made using stainless steel mesh and it gets cut by the laser machine. When you make use of a filter disc, then it will not be difficult for you to ascertain the quality of filtration.
Sintering of ferritic stainless steels is necessary to be carried out in a proper atmosphere. Normal atmosphere, namely cracked ammonia containing 75%H2 and 25%N2, employed for sintering of iron ...
low-cost sintering atmospheres, some stainless steel parts were even sintered in N 2-H 2 atmos-pheres containing as little as 3% H 2. As is shown later, such parts had very low corrosion-resistance requirements. Vacuum sintering of stainless steels is conducted with low pressures (1000 to 3000 μm Hg) of argon or nitrogen to
Sintex develops and manufactures sintered metal components – also called powder metal or powder metallurgy. Stainless steel is our core expertise – both traditional sintered stainless steel components and sintered stainless steel filters. We are global experts in corrosion resistance, but offer several grades, materials and processes.
As a manufacturing partner for automotive and industrial markets, we are one of the leading international suppliers of sintered metal products. Manufacturing parts and other components, such as stainless steel fittings, sintered metal filters, stainless steel flanges, assemblies manufactured by a variety of powdered metal parts using the powdered metal process .
Sintering allows to obtain complex shapes directly from the compacting tooling. such as teeth, splines, profiles, frontal geometries and non-axisymmetric shapes, ... Sintered stainless steel parts. Sintered stainless steel parts. anemptytextlline. Soft magnetic sintered components.
18-03-2020· You can get rid of the lime stains with a citric cleaner safely, but once you have the black surface from the LimeAway it is very hard to fix. Just so, how do you descale stainless steel? Mix 1/4 cup of baking soda with 1 tablespoon of liquid detergent if scale remains. Slowly add vinegar to the mixture until it forms a paste.

Laser welding of sintered austenitic stainless steel (grade 316L) was reported to be very easy, resulting in good joints. 7 In trials with sintered Al alloys, it proved difficult to obtain a sound joint because of porosity formation, resulting in spongy welds. 7 It is thought that oxidation was the probable cause, possibly creating locally overheated spots when more laser energy is absorbed by the oxides than the metal…
Sintered Stainless Steel Plates are custom-designed filter plates. The main purpose is to provide users with extreme levels of filtration while being able to stand up to high pressure without being blown off like normal paper filter media. Stainless Steel Filter Plates are sintered together to form a rigid metal sheet of 2-10 Layers of wire mesh.
Sintered Stainless-Steel Filters for Corrosion Resistance 316 sintered stainless-steel filters are widely used across a large number of different industries due to their excellent performance and strong build quality. 316 sintered stainless steel has exceptional corrosion resistance and performs well in extreme temperatures without losing strength.
Stainless steel sintered mesh & stainless steel sintered filter: The stainless steel sintered mesh is a new type of filter material which is made of a multi-layer wire woven mesh and is manufactured by a special lamination pressing and vacuum sintering process, …
Austenitic stainless steels (300 series). These have the greatest corrosion resistance.The most common ones are grades 304 and 316 for applications subjected to aggressive corrosive conditions, and grade 303 for easy machining. Grade 310 is used as refractory stainless steel. These steels are non-magnetic.Their hardness and mechanical strength can be increased by modifying the sintering ...
Stainless steel (SS) powders are used in the preparation of sintered SS products. One of the applications of sintered SS products is as filters in the petrochemical and food processing industries. In these industries, the SS filters are subject to severe conditions associated with the removal of solid particles from the fluid. Hence, SS filters should have adequate mechanical strength and high ...
Embossed sintered stainless steel sheet. They are used as filters in the case of separating liquids from solids as well as gases; Examples would be filters for retention …
Sintered wire mesh filter (XKW) is rolled by multi-layer (usually five layers) 316L or 304L stainless steel wire, sintered by high temperature vacuum, argon arc or plasma welding. Sinter Metal …

Metal injection molded stainless steels can attain higher mechanical properties than conventional PM (press and sintered) steels, mainly due to the higher density that can be achieved, 44 but their properties are slightly worse compared with their wrought counterpart grades (Table 16.1), except if post-sintering treatments are applied, like hot isostatic pressing, 39 when full density is obtained.
15-06-2021· Some material must be sintered under vacuum with pressure ranging between 10 -2 millibars and 10 -4 millibars. Those are, for example, the best condition for sintering extremely reactive materials, such as titanium. However, most of the sintered materials requires atmospheres enriched with inert gases, which is also the case for stainless steels.
