Welcome to Sachiya Steel International Private Limited, India’s leading manufacturer of spring washers. In this guide, we explore the essential components that provide high compression and reliability—spring washer. They play a critical role in preventing fastening or loosening due to vibrations and torque.

What is a Spring Washer?

A spring washer, also known as a disc spring, provides a compensating spring force and sustains a load or absorbs shock. Its primary function is to keep bolted joints and other fastened joints tight against vibrations and rotational forces.

Types and Uses of Spring Washers:

Spring washers come in several types, each tailored for specific needs:

1. Helical Spring Washers: These are perfect for applications with moderate load and limited space, helping prevent fasteners from loosening.
2. Belleville Washers: Ideal for high load applications in confined spaces, these washers can also stack to adjust spring constant or deflection capacity.
3. Curved and Wave Spring Washers: These offer lighter loads and compensate for thermal expansion and contraction in assemblies.

Each type serves specific applications from automotive to electrical assemblies, ensuring joint security and integrity.

Comparisons and Specifications:

Choosing the right washer involves understanding the differences between various types:

• Spring Washer vs. Lock Washer: Spring washers provide continuous pressure and suit short deflection applications, while lock washers are better for full thread engagement.
• Spring Washer vs. Flat Washer: Flat washers distribute load and protect surfaces, while spring washers maintain tension, providing a dynamic hold.

Sachiya Steel International provides spring washers in various sizes like M6, M8, M10, M12, and M16, crafted from materials such as stainless steel, brass, and carbon steel for durability and corrosion resistance.

Practical Application Guide:

Selecting the right size and material for your spring washer is crucial. For outdoor use, an M8 stainless steel spring washer is ideal due to its rust resistance. To install a spring washer:

1. Place it under the bolt head or nut.
2. Ensure correct orientation as some washers require specific placement.
3. Tighten according to the recommended torque for the material and size.

Spring washers are indispensable in securing mechanical components. At Sachiya Steel International Private Limited, we specialize in top-quality spring washers designed to meet diverse industrial needs. Explore our comprehensive range for enhanced durability and performance in your applications.

Sachiya Steel International is one of the prominent trader and whole seller for high quality Stainless Steel 310S Washers, which results in less internal stress and, most important, a deeper hardened zone in the work – piece. Alloying elements have a strong influence on heat-treating; because SS 310S Flat Washers tend to slow the diffusion of atoms through the iron lattices and thereby delays the allotropic transformations.

This means, for example, that the extremely hard martensite of Stainless Steel 310S Lock Washers, which is normally produced by fast quenching, can be produced at lower cooling rates. Improved hardenability of Stainless Steel 310S Sealing Washers is achieved by adding such elements as manganese, molybdenum, chromium, nickel, and boron. These alloying agents in SS 310S Split Washers also permit tempering at higher temperatures, which generates better ductility at the same hardness and strength.

The testing of properties in Stainless Steel 310 Slot Washers often begins with checking hardness. Stainless Steel 310S Machine Washers is measured by pressing a diamond pyramid or a hard steel ball into the steel at a specific load. Tensile and yield strength of SS 310 Star Washers are determined by pulling a standardized machined sample in a special hydraulic press and recording the pulling force at increasing elongations until the sample breaks. The elongation of SS 310S Spring Washers, and the way the fracture looks, is good indications of the steel’s ductility.

Sachiya Steel International is the top most producer & wholesaler in Stainless Steel 304L Washers, which is additionally advantageous for top temperature service thanks to its sensible mechanical properties. These Stainless Steel 304L Flat Washers offers higher creep and stress rupture properties than Stainless Steel 304.

Our SS 304L Lock Washer includes a rather improved corrosion resistance over completely different alloys of stainless steel in powerfully oxidizing environments as a result of the addition of metal (niobium) and number. These Stainless Steel 304L Sealing Washer doesn’t perform well in chloride solutions, even in tiny concentrations, or in sulphuric acid.

SS 304L Split Washer carries out intermittent heating between 800 Degree F (427 Degree C) and 1650 Degree F (899 Degree C), or for attachment below conditions that stop a post – weld temper. These Stainless Steel 304L Slot Washers can be hardened by heat treatment, solely by cold operating.

Stainless Steel 304L Machine Washer may be simply welded and processed by commonplace search fabrication practices. These SS 304L Star Washers also contains niobium for stabilization against sensitization and resultants inter – granular corrosion. Restricted SS 304L Wire Spring Washers plus columbium stabilization permits welded fabrications to be used in corrosive environments, normally without post – weld heat treatment. These SS 304L Flat Spring Washer appears to fall between both the stainless and nickel categories as it contains characteristics of both.

Sachiya Steel International is one of the renowned manufacturer & exporter of high quality Stainless Steel 304 Washers, which is the family of steels that have a mixed micro – structure of 50 % ferrite and 50 % austenite. Ferritic – austenitic stainless steel also referred to as Stainless Steel 304 Flat Washers, combine many of the beneficial properties of ferritic and austenitic steels.

Stainless Steel 304 Lock Washer offers excellent resistant to corrosion and very high mechanical strength. The high corrosion resistance of Stainless Steel 304 Sealing Washer ensures significantly more uptime than carbon steels and conventional stainless steels, while the mechanical strength allows for lighter constructions, more compact system design and less welding.

The standard austenitic steels like Stainless Steel 304 Split Washers are relatively easy to make and to fabricate. SS 304 Slot Washers has high amount of chromium and a slight amount of nickel. Stainless Steel 304 Machine Washer combines both austenitic (chromium – nickel) and ferritic (chromium only) molecular structures.

As their names imply, Stainless Steel 304 Star Washer consist mainly of one phase, austenite or ferrite. Although these SS 304 Wire Spring Washers are fine for a wide range of applications, there are some important technical weaknesses in both types. Stainless Steel 304 Flat Spring Washer are known to offer exceptional strength and astounding aesthetic qualities along with better resistance against corrosion and high temperature, superior hygienic surface finishing, and improved steel recyclability.
