Why does stainless steel spring have corrosion resistance?

Why does stainless steel spring have corrosion resistance?

All metals react with oxygen in the atmosphere to form an oxide film on their surface. Unfortunately, the iron oxide formed on ordinary carbon steel will continue to oxidize, leading to the expansion of corrosion, and finally forming holes. The surface of carbon steel can be protected by coating with paint or anti-oxidation metals (such as zinc, nickel and chromium), but as we all know, this protection is only a thin film. If the protective layer is damaged, the steel below will start to rust.

Carbon spring wire type

Carbon spring wire type

The current recommended standards for carbon spring steel wire are divided into two types: one is cold-deformed strengthened steel wire, also known as cold-drawn spring steel wire; The other is martensite strengthened steel wire, also known as oil quenched and tempered steel wire. The cold-drawn carbon spring steel wire is first quenched with lead to obtain the sorbite structure, and then the surface is phosphatized

What are the main methods to prevent metal rust of spring?

What are the main methods to prevent metal rust of spring?

In addition to the anti-rust paint we know, what other surface treatment methods are available for spring to prevent rust? The following are some commonly used spring surface treatment methods: First, anti-rust, direct spraying of anti-rust oil, poor anti-rust effect, neutral salt spray test for 2-8 hours depending on the quality of anti-rust oil

Different uses of spring machine tools

Different uses of spring machine tools

Spring machine tools mainly include: wire feed wheel, wire plate, mandrel (or mandrel/auxiliary core), curve gauge, cutter, auxiliary knife and pitch knife. Each spring machine tool has different functions, as follows: a wire feed wheel: provides power for wire feed, so that spring material can feed wire forward/backward, etc.

How to prolong the service life of spring?

How to prolong the service life of spring?

The isothermal quenching of a precision spring can be used for springs with small diameter or sufficient hardenability, which can not only reduce the eccentricity, but also improve the strength and toughness. Conduct another tempering after isothermal quenching to increase the elastic limit. Tempering temperature is the same as isothermal quenching temperature.

Characteristics of precision spring

Characteristics of precision spring

The characteristics of precision spring are: the spring with very small wire diameter, strong stability, stable force value, high number of applications and high requirements. Precision compression spring, also known as precision spiral spring, is mainly used in aerospace, electronic devices, mechanical equipment, electrical equipment, clocks, digital products, medical machinery and other industries.
