stainless steel is an alloy made by incorporating chromium, nickel and other metal elements into steel. its non-rusting property is derived from the chromium in the alloy. chromium forms a strong, self-repairing chromium oxide film on the surface of the alloy, which is invisible to our naked eyes. t

why are the train tracks always rusty? this is related to the materials used to construct the rails. now we will reveal the materials used for the rails.why are railroad tracks always rusty?rail is the abbreviation of railway track. rail is a habitual term. it is made of steel with high hardness and

when buying stainless steel round pipes, i often feel a headache because i don’t know what material to choose, because the better the material of the stainless steel pipe, the more expensive it is and the higher the cost. the 304 stainless steel round tube material still has strong corrosion resista

today we come to understand the basic process of stainless steel forging stamping.cutting: it is a process of separating the sheet material along the unclosed contour, and its purpose is to cut a large area of sheet material into strips or small sheets suitable for punching. this work is usually car

mechanical performance test of stainless steel forgings: for the benefit of customers and our own reputation, each stainless steel forging product of our factory must be tested for mechanical performance. generally, the main tests are yield, tensile, impact and other tests.at present, the company’s

the heat treatment of forgings can be divided into two groups according to the purpose of heat treatment. in the first group, the purpose of heat treatment of forgings is not only to provide good cutting performance for metal cutting, but also to prepare for the second heat treatment. forgings belon

the forging process plays an important role in the production of forgings. the process flow is different, the quality of the obtained forgings (referring to the shape, dimensional accuracy, mechanical properties, streamline, etc.) is very different, and the type of equipment used and the tonnage ar

1. 304 stainless steel. it is one of the most widely used austenitic stainless steels. it is suitable for the manufacture of deep-drawing forming parts and acid pipes, containers, structural parts, various instrument bodies, etc. it can also manufacture non-magnetic, low-temperature equipment and pa

nickel-based materials belong to stainless steel.the content of ni is different:nickel-based alloys are generally referred to as alloys with ni content exceeding 30wt%. common products have ni content exceeding 50wt%. due to their superior high-temperature mechanical strength and corrosion resistanc
