●
Characteristics and scope of application: It has high hardness and wear resistance after quenching and tempering, but has low thermal hardness, poor hardenability,
easy deformation
, low plasticity and strength
.
Used as various tools that require high hardness and wear resistance, such as simple-shaped molds and punches, metal cutting tools, drilling tools, woodworking milling cutters, countersunk drills, axes, chisels, Longitudinal hand saws, as well as benchwork assembly tools, rivet dies and other secondary tools.
Performance: Mechanical properties
(
Especially elastic limit, strength limit, yield ratio
)
, elastic loss resistance
(
That is, resistance to elasticity loss, also known as anti-relaxation performance
)
, fatigue performance, hardenability, physical and chemical properties
(
Heat resistance, low temperature resistance, oxidation resistance, Corrosion resistance, etc.
)
Features:
Steel plate has high strength, hardness, elasticity and hardenability, and high wear-resistant parts, such as grinder spindles and spring chucks. Precision machine tool screws. Cutter. Collar on spiral roller bearing. Railway rails, etc.
Application: Used as various small-sized flat and round springs, seat springs, spring springs, and can also be used to make spring rings, valve springs, clutch springs, brake springs and cold-drawn steel wire cold-rolled spirals spring.
:
Features:
It is a widely used silicon-manganese spring steel with slightly higher strength, elasticity and hardenability.
Alloy spring steel is suitable for making flat springs that can withstand larger loads in the railway vehicles and automobile tractor industries.
It belongs to spring steel
,
and is suitable for making automobile leaf springs.
:
Characteristics:
It has high strength and elasticity after proper heat treatment or cold work hardening. The characteristic is that its fatigue strength is comparable to alloy spring steel under the same configuration.
Application: Used for manufacturing springs, spring rings, various washers, clutches, and manufacturing shafts, rollers, eccentric shafts, etc. in general machinery.
：
Among high-carbon steels, there is nothing better than
,
very good toughness
,
spring steel has high tensile strength, elastic limit, High fatigue strength.
