Tool steels comprise carbide-forming elements such as chromium, vanadium, molybdenum and tungsten in different combinations. They also contain cobalt or nickel which improves their high-temperature performance. They are generally heat-treated to improve the hardness and used for stamping, forming, shearing and cutting metals and forming of plastics. They are classified according to their composition and […]

Stainless steel is an alloy of Iron with a minimum of 10.5% Chromium (typically between 10-20%). Chromium produces a thin layer of oxide on the surface of the steel known as the ‘passive layer’. This prevents any further corrosion of the surface. Stainless Steel is valued due to its high corrosion resistance. Stainless steel is […]

Alloy steel is a steel that has had small amounts of one or more alloying elements (other than carbon) such as such as manganese, silicon, nickel, titanium, copper, chromium and aluminum added. This produces specific properties that are not found in regular carbon steel. Alloy steels are workhorses of industry because of their economical cost, […]

What are Valves? Valves are type of mechanical devices that controls the flow and pressure within a system or process. They are important components of a piping system that flows liquids, gases, vapours, slurries etc. There are many types of valves available for different application: Gate Valve, Globe Valve, Plug Valve, Ball Valve, Butterfly Valve, […]

Bearings is a mechanical device that help to reduce friction between rotating shaft or linear bodies.Ball bearings have spherical rolling elements and are used for lower load applications, while roller bearings use cylindrical rolling elements for heavier load carrying requirements. Linear bearings are used for linear movements along shafts and may also have rotational capabilities.Source Link …

Supplier Scorecard is we used to measure suppliers, and to give qualified or certified status to suppliers. Ideally, The best scoring suppliers per commodity group would get more share in the order. 1) Quality Monthly DPMO (defective parts per million opportunities) = Monthly Quantity Rejected ÷ Monthly Quantity Received x 1,000,000Rolling three-month DPMO to track […]
