ASTM A230 Carbon Valve Spring Quality Steel Wire

 

Carbon Spring Steel Wire that is heat treated in line in the following way: it is first transformed into austenite, quenched in oil or similar quenching medium, followed immediately by tempering by heating to the appropriate temperature.

 

Equivalent Materials
DIN 1.1250DIN C65S2EN C65S2EN 1.1250

 

A230 Carbon Spring Steel Wire Dimensional tolerances

Wire in coils

The tolerances level for the wire diameter is based on EN 10218-2:1996 level:

-T5 for wire diameter up to and including 0,80 mm;

-T4 for 0,80 mm up to 10,00 mm;

-T3 above 10,00 mm.

Wire in cut lengths

The requirements for length tolerances and straightness are as in EN 10218-2:1996. The tolerance on the nominal length shall only be in plus keeping the same tolerance range

0.60 - 0.75 0.15 - 0.35 0.60 - 0.90 max 0.025 max 0.025

 

A230 Non metallic inclusions

The VD grades shall be checked for maximum size of inclusion according to ENV 10247. The allowable level of inclusions shall be agreed between the parties at the enquiry and order.

 

A230 Form of delivery

Alloy wire shall be supplied in coils, on spools or in cut lengths. The wire in coils or on spools shall form one continuous length. Wire in coil may also be supplied on carriers containing one or more coils.

 

For VD and TD grades no welds are permitted after the heat treatments preceding the final drawing operation; for 'FD' grades no welds shall be made at finished size unless agreed otherwise between the parties.

 

The supplied wire units shall be tightly bound to ensure that wire spiral waps do not spring out unforeseen. The starting end shall be marked and at the coil ends the wire shall be covered with a protective cap.

 

A230 Carbon Spring Steel Wire Surface finish

The wire shall be protected against corrosion and mechanical damage. Unless otherwise specified the wire shall be delivered in slightly oiled condition.

 

A230 Carbon Spring Steel Wire Surface quality

The surface of the wire shall be smooth and permissible depth of surface defects at the coil ends shall be in accordance with Table.

By in-line control of surface defects the areas of the coil with defects above the level of Table 7 shall be marked. In-line testing is not performed for FD-grades.

The number of defective parts that can be tolerated may be agreed between the parties.

Carbon Spring Steel Wire made from unalloyed or alloyed steels. They are primarily subject to torsional stresses such as in compression and extension springs and in special cases also for applications where the spring wire is subject to bending stresses such as lever springs. As a rule unalloyed steels are used for applications at room temperature whereas alloyed steels are generally used at a temperature above room temperature. Alloyed steels may also be chosen for above average tensile strengths.

 

High carbon steel springs are very popular due to their econimcal, strong, and durable nature. The Fushun is equipped with the knowledge and expertise to facilitate in your selection of the perfect high carbon steel springs for your project, customizing the springs to your exact specifications. Fushun Wire Spring manufactures custom springs using many types of high carbon steel wire, including oil tempered steel wire. We specialize in providing each client with a custom spring that matches your exact application requirements, leveraging over 85 years of experience producing springs for industrial applications. Our staff is available to assist you in selecting the best high carbon steel for your application and will manufacture your springs to specifications and the highest quality standards. You can be assured that your springs will be delivered to you fast and ready for your production line. High carbon spring steel wires are the most popular steel wires used when manufacturing springs. They are economical, strong, and durable.

A230 Carbon Spring Steel Wire Classification

The grade for normal applications made from unalloyed or alloyed steel has the abbreviation FD and is intended for static applications.

Spring steel wire for medium fatigue levels, such as required for some clutch springs from unailoyed or alloyed steel, has the abbreviation TD.

Spring steel wire from unalloyed steel or alloyed steel intended for use under severe dynamic duty such as for valve springs or other springs with similar requirements has the abbreviation VD.

Medium and high fatigue grades TD and VD are characterized by high steel cleanliness, specific chemical, mechanical and technological parameters and a well defined surface condition in relation to the allowable depth of surface defects and decarburization.

The static grade FD is characterized by its chemical, mechanical and technological characteristics as well as by a specified surface condition concerning surface defects and decarburization.

Information to be supplied by the purchaser

The purchaser shall clearly state in his enquiry or order the product and following information :

a)the desired quantity;

b)the number of this Standard:

c)wire grade

d)the nominal wire diameter;

e)the form of delivery and unit mass;

f)the type of inspection document;

g)any particular agreement made.

 

High-carbon spring steels are the most commonly used of all springs materials. They will meet your spring steel material specification in preference to others, despite being the least expensive. High Carbon spring wires are readily available, easily worked, and most popular. These materials are not satisfactory for high or low temperatures or for shock or impact loading.We're ISO 9001:2008-certified spring manufacturer dedicated to supplying our customers with high-performance spring products on time and at a competitive price. Hard-drawn spring steel wire, or HDMB spring wire, is manufactured using a cold-drawing process. During this activity, the wire being worked is coated in oil and pulled through one or more dies to reduce the wire width. One of the most economical and versatile steel wire types, hard-drawn wire is perfect for a range of general-purpose applications.

 

Spring steel is an alloy that can withstand intense twisting and bending without becoming distorted. It is resilient and pliable, yet durable, which is perfect for a general use steel. Products made with this alloy can be bent, extended, compressed, or twisted, yet they will return to their original shape. This characteristic is commonly known as high yield strength. Spring steel’s high yield strength is achieved through one of two manufacturing processes: (1) Hardening by heat treatment and (2) Work hardening. There are many different types of spring steel. They may be identified by their steel grade, which is determined by a material’s chemical, physical, and environmental properties. They may also be identified by their application, such as compression, torsion, or tension.
