Properties of Stainless Steels for Various Applications

1Cr17Mn6Ni5N stainless steel is instead of grade 1Cr17Ni7, it is with magnetic properties after cold rolled, used for railroad cars. 1Cr17Ni7 stainless steel has high strength after cold working for railroad cars, conveyor belts, bolts and nuts. 1Cr18Ni9 stainless steel has high strength after cold working, but the elongation is…

Design and Planning of New Cold Rolling Mill

Cold-rolled sheets have good surface quality, high dimensional accuracy and no oxide sheet due to rolled at room temperature. After annealing treatment, its mechanical properties and technological properties are better than hot-rolled sheet, mostly used of automotive, electrical products, locomotives, aviation, precision instruments, food and other industries. In the planning and design…

This article is excerpted from a speech by Mr. Liu, chairman of SME Group Powerful person has many dimensions and criteria, but the most critical one is to see whether the person has the ability to solve problems and be a buster of tricky troubles. Behind the hidden is a…

Moudling Process in Foundry Industry

In the foundry industry, common modeling techniques take CNC wood modeling, foam molding machines, CNC EPS machining centers and tranditional sand casting lines, these methods have different application scope, casting precision, and cost. CNC Wood Modeling CNC Wood Modeling utilizes CNC machinery to carve models out of wood or other…

Spare Parts For Rolling Mill

Every steel rolling mill has certain quantity of spare parts to replace the failure parts, some key spare parts of rolling equipment and supportive devices need to be ordered for urgent replacement timely. Spare Parts for rolling line 1. Rolls – Working Rolls: The number varies depending on the number of rolling stands, typically each stand…

Ferritic stainless steel

Ferritic stainless steel is known for its high corrosion and oxidation resistance, but it has lower plasticity and toughness. Common grades include 409 and 430, which are mainly used in automotive and construction applications. Magnetic Properties: Ferritic stainless steel is magnetic. Thermal Expansion: The thermal expansion rate of ferritic stainless…

Transformation of Single Cold Rolling Mill

A single cold rolling mill can handle small-scale rolling tasks with lower initial equipment investment. Its production organization is more flexible, allowing for quick adjustments to specifications based on market demand. The old system’s operation and production process relied heavily on operator input setting and field adjustments, with fault diagnosis…

Cold Rolling Stainless Steel – Requirements and Comparisons

Stainless steel has high deformation resistance, generally twice that of ordinary carbon steel. During cold working, deformed martensite forms, causing a rapid work hardening rate and requiring greater rolling force and load. Requirements Stainless Steel Cold Rolling Mill Should Meet Work rolls should be of small diameter as much as…

Detecting Roll Flaws

Roll flaw detection is essential for almost all high-standard rolling mill. Common methods for roll flaw detection include magnetic particle flaw detection, penetrant color flaw detection, eddy current flaw detection, and ultrasonic flaw detection. Magnetic Particle Flaw Detection: This technology is primarily used to identify surface cracks on the roll body…

Tehnology Frontier 278

New-product: 1100MPa High-strength Solid Wire At present, there isn’t a matching welding material with the1100MPa high-strength steel plate, most of the industry is forced to use 900MPa grade wire, in the design to avoid the welding joint force, which brings more trouble to the equipment design, but also is the…
