20um 316L microporous stainless steel filter disc is a type of filter element used for the filtration of liquids and gases. The disc is made by molding and sintering stainless steel powder together to create a porous structure. The resulting structure has a high filtration efficiency and a narrow pore size distribution, which allows for efficient filtration of small particles and impurities. 20um 316L microporous stainless steel filter disc is a type of corrosion- resistant steel that contains molybdenum, which improves its resistance to corrosion and pitting. This makes it a good choice for applications where the filter element will be exposed to corrosive fluids or environments. Parameters Brand: TOPTITECH Material: 316L stainless steel Max pressure: 5MPa Max temperature: 600 degree Types:disc Diameter Size: 30 mm Height Size: 2mm Pore Size: stainless steel 20um Three important aspects of the filter Pore size: The pore size of the filter disc can be customized according to the specific application requirements. The pore size typically ranges from a few microns to several hundred microns. Filtration efficiency: The sintered porous stainless steel filter disc can achieve high filtration efficiency due to its uniform pore structure.

Tapered Roller Bearings can bear one direction radial load and axial load, which are larger than radial ball bearing. Tapered Roller Bearings have widely application, especially in autombile. Automobile Bearing All moving parts of a automobile require bearings to function. Bearings improve the performance of automobiles, withstand heavy loads and reduce friction. Some of the major subsystems that use bearings are engines, transmissions, transmissions, wheels, steering, electric motors, pumps, etc. In addition, even windshield wipers, mirrors, doors and hood hinges require bearings to operate smoothly. Although there are dozens of ball bearings in the market, the following three types of bearings are commonly used in the automotive industry.

These bearings are designed for use in overhead conveyor systems. overhead conveyor bearings are constructed with fully machined raceways made of case- hardened steel. The Nicer bearings can be supplied with cages or full ball arrangements. Sealed and shielded overhead conveyor bearings are usually lubricated for life. Open types are usually not greased. Features of the overhead conveyor bearings series: Low cost and light strength allow the system to be designed to carry conveyor loads of up to 60 lbs. per foot. Fully enclosed track allows for application in a variety of contaminated environments. The flexibility of a design that can run straight up, straight down, or upside down saves space, allows for changes, and makes it practical to service production equipment in remote, difficult locations. Installation is simple and all track overhead conveyor bearings are pre- engineered, pre-assembled and ready for assembly. For a given load, the lightweight nature of overhead conveyor bearings requires less support steel. Heat treatment of all curves, wheels, chain side links and bracket pegs ensures long life operation of overhead conveyor bearings Roller Turn Roller are available with tappered roller bearing or full ball complement Both have triple labyrinth seals, Outer ring，inner ring and ball are made by bearing steel (AISI 52100) with hardness HRC58-62 and HRC 59-63.

Conveyor rollers are part of a conveyor belt used to move products or bulk bulk goods such as coal, sand or iron ore. Conveyor rollers are part of the unit and are essential to enable transport. What is a Conveyor Belt Bearings? Conveyor roller bearings are pressed into the ends of the conveyor rollers and allow the rollers to rotate smoothly on their shafts during conveyance. Rolling bearings support and guide rotating or oscillating machine elements and transfer loads between machine parts.

Seamless Stainless Steel Tube Stainless Steel Rectangle Pipe Stainless steel rectangle pipes are a type of hollow structural section made from stainless steel. They have a rectangular cross-section and are typically used in construction, industrial, and manufacturing applications. Stainless steel rectangle pipes are known for their excellent corrosion resistance and durability, making them ideal for use in harsh environments or applications where they will be exposed to corrosive substances. They also have good strength-to-weight ratios and are easy to clean and maintain. In terms of fabrication, stainless steel rectangle pipes can be welded, bent, and cut to fit specific shapes and sizes. They come in a range of grades and finishes, such as 304 or 316 stainless steel, and can be polished, brushed, or coated to achieve different appearances

Grade B7M—The maximum hardness of the grade shall be 235 HBW or 99 HRB. The minimum hardness shall not be less than 200 HBW or 93 HRB. Conformance to this hardness shall be ensured by testing the hardness of each stud or bolt by Brinell or Rockwell B methods in accordance with 9.2.1. The use of 100 % electromagnetic testing for hardness as an alternative to 100 % indentation hardness testing is permis-sible when qualified by sampling using indentation hardness testing. Each lot tested for hardness electromagnetically shall be 100 % examined in accordance with Practice E566. Follow-ing electromagnetic testing for hardness, a random sample of a minimum of 100 pieces of each heat of steel in each lot (as defined in 12.1.1) shall be tested by indentation hardness methods. All samples must meet hardness requirements to permit acceptance of the lot. If any one sample is outside of the specified maximum or minimum hardness, the lot shall be rejected and either reprocessed and resampled or tested 100 % by indentation hardness methods. Bolts, screws, studs, and stud bolts shall be pointed and shall have a workmanlike finish. Points shall be flat and chamfered or rounded at option of the manufacturer. Length of point on studs and stud bolts shall be not less than one nor more than two complete threads as measured from the extreme end parallel to the axis. Length of studs and stud bolts shall be measured from first thread to first thread.

The Chinese clan is the first country in the world to smelt iron and steel. Our ancestors mastered some skills of iron smelting, steelmaking, casting and forging and heat treatment three thousand years ago, more than 1700 years earlier than European countries. important contributions to human progress. Steel has become the most basic and important material for modern industrial and agricultural production, transportation, national defense and even people's life. At present, although various new inorganic materials and organic synthetic materials have been greatly developed. But in terms of production cost and wide applicability, they are far from being able to replace steel. Therefore, the production capacity of steel is still one of the important symbols to measure the national strength of a country. The reason why iron and steel materials are so widely used is that iron ore deposits are concentrated, the storage capacity is large, mining and smelting are relatively economical, and semi-finished steel products have strong cold and hot deformation capabilities. The finished product has excellent mechanical properties (strength, plasticity and impact resistance) and processing properties (cutting, welding, cold deformation, etc.). However, compared with silicic acid materials, polymer synthetic materials and some non-ferrous metals, its biggest disadvantage is that it is easy to lose weight due to corrosion and even completely destroy it in the atmosphere or under various media conditions such as acid, alkali, and salt. .
