What is the Effect of Temperature on Fasteners?

Last Updated on November 16, 2022 by188bet博金宝官方网站



Whether you are using screws, rivets, nuts and bolts, or anchors, choosingfasteners that adapt well to applications of varying temperatures可能很关键。

It's Gettin' Hot in Herre*

It goes without saying that plastic fastenersrisk meltingwhen暴露于高温。但是,除非金属达到异常高的温度,否则不会。那必须使它们在高热应用中安全,对吗?

Metal is prone to these issues with prolonged exposure to heat:

蠕变is slow deformation from constant mechanical stress that commonly occurs in extreme temperatures.

Stress relaxation是一种热机械现象,其中弹性应变缓慢转化为塑性应变,即使在应力水平远低于屈服强度下

Corrosion is a result of oxidation from heat


Temperature 用于高热应用的材料
Up to 450° F Low steel or medium carbon alloys
在450°F和900°F之间 不锈钢
Between 900° F and 1200° F 强大合金包括INCO 718和A-286
超过1600°F Nickel-cobalt alloys

Baby It's Cold Outside**


Loss of ductility. In other words, less ability to undergo plastic deformation before fracturing. Metals become brittle in very low temperatures.


Increased sensitivity to shock loading.

Oddly enough, the yield strength and mechanical tensile strength of some metals increase as temperatures drop!

Temperature 在冷设置中使用的材料
降至-100°F 镍富合金
在-100°F和-300°F之间 不锈钢
低于-300°F Non-metallic materials
