stacked single turn wave disc springs wavy washers suppliers

Material technology:

1.Carbon Steel(Oil Temper)

• This prehardened material is the standard material for wave springs.
• Less expensive option to Stainless Steel.
• Maximum Recommended Operating Temp

2.Stainless steel

a.SUS304H Stainless steel

304 is the standard stainless steel for spiral retaining rings. This widely used material is specified because of its combination of corrosion resistance and physical properties. 304 obtains its spring temper condition by cold working. Though it is categorized as being a nonmagnetic stainless, 304 becomes slightly magnetic as a result of cold working. It is not hardenable by heat treatment.

b.SUS316 Stainless steel

Nearly identical in physical properties and heat resistance to 302, 316 provides additional corrosion resistance, particularly against pitting, due to its molybdenum chemical content. 316 is generally used in food, chemical and sea water applications.316 shows less magnetism than 302. However, as with 302, magnetism increases as the wire is cold reduced. This stainless grade is also not hardenable by heat treatment.

c.SUS631(17-7PH/C) Stainless steel

Similar in corrosion resistance to type 302, this alloy is used almost exclusively for wave springs, yet offers both high tensile and yield strengths for special ring applications. In fatigue and high stress applications, 17-7 out performs even the finest grade of carbon steel.Spring properties are achieved by precipitation hardening Condition C to Condition Ch900. As a result, the material may be subjected to a temperature of 650ºF (343°C) without a loss of spring properties. 17-7 PH Condition CH900 exhibits magnetism similar to high carbon steel.

3.Superalloy Rigid INCONELX-750*

This nickel-chromium alloy is used most commonly in high temperature and corrosive environments. Two commonly specified tempers of Inconel are described below.Most commonly, Inconel X-750 is precipitation heat treated to a spring temper condition. In this state, it has temperature resistance to 700°F. The National Association of Corrosion Engineers (NACE) approves this hard temper to specification MR-01-75 (Rc50 maximum) for spiral retaining rings and wave/compression springs.
