When choosing stainless steel in a corrosive environment,in addition to the specific use of stainless steel spring should have a detailed understanding, but also need to consider the main factors are: stainless steel corrosion resistance, strength, toughness and physical properties, processing, forming properties, resources, price and easy to obtain. Corrosion resistance of stainless steel includes corrosion resistance to acid, alkali, salt and other corrosive media as well as resistance to oxidation, vulcanization, chlorination, fluorination and other properties at high temperatures.

The heat treatment of spring is to change the internal structure of metal and alloy by heating, holding and cooling of spring,so as to achieve the purpose of changing the mechanical, physical and chemical properties of material. The common heat treatment methods are as follows. 1. Quenching: Quenching means heating spring steel to a certain temperature (critical temperature) (AC3 or AC1), holding it for a certain time, making it into austenite, and then cooling it rapidly at a temperature greater than the critical temperature, thus obtaining the heat treatment method of martensite

Spring testing scope: gas spring, compression spring, spring washer, air spring, automobile springs, spring shock absorber,diaphragm spring, light spring, eccentric suspension spring, leaf spring, valve spring, spring, spring mattress, coil spring, stainless steel spring, waveform spring, torsion spring, the relief valve spring, compression spring, butterfly spring, torque spring, carbon spring, rubber spring, alloy spring etc.Spring testing items: performance testing, pressure testing, stiffness testing, hardness testing, elastic testing, coating thickness testing.

What are the main functions of springs? There are many kinds of springs,if according to the nature of the load it bears, the spring is mainly divided into four kinds, such as stretch spring, compression spring, torsion spring and bending spring. If according to the spring shape can be divided into spiral spring, dish spring, ring spring, plate spring, coil spring, etc. The basic types of springs are listed in the table.Spring is a kind of elastic element that works through its own large elastic deformation. It is widely used in all kinds of machines.

A spring is a mechanical part that USES elasticity to work. The parts made of elastic material are deformed under the action of external force, and restore to original condition after removing external force. Also known as a spring. It is usually made of spring steel. The type of spring is complex and diverse, according to the shape, there are mainly coil spring, coil spring, plate spring and so on. What is the difference between a compression spring, a tension spring, and a torsion spring? How can we tell them apart?
