Chemical composition and mechanical properties of the main steel grades
Domestic metallurgical enterprises produce many grades of the steels under consideration, the main of which are:
|steel grade||Content of basic chemical elements,%|
|65G||0.62… 0.70||0.17… 0.37||0.90… 1.20||Not more than 0.25||-|
|60С2А||0.58… 0.63||1.60… 2.00||0.60… 0.90||Not more than 0.30||-|
|50HFA||0.46… 0.54||0.17… 0.37||0.50 to 0.80||0.80… 1.10||0.10… 0.20|
|60С2Г||0.55… 0.65||1.80… 2.20||0.70… 1.00||Not more than 0.30||-|
Note. In steels, up to 0.40% nickel is allowed.
After the heat treatment, the steel data must have the following physico-mechanical characteristics:
|steel grade||Limit of plasticity, MPa||Ultimate strength, MPa||Relative extension, %||Relative narrowing of the cross-section,%||Hardness by Rockwell, NRC|
|65G||785||980||8||thirty||477 (Brinell hardness)|
|60С2Г||1325||1470||6th||25||340… 360 (Brinell hardness)|
Company Electrovek-steel offers to purchase at affordable prices from the manufacturer rental of spring and spring steel. The supplier provides timely delivery of rolling products to any point specified by the consumer.
GOST 14959−89 provides the following types of rolling profiles:
Volumetric hire. Precisely the circle of steel is manufactured:
AO — especially high accuracy (AO1);
A — high accuracy (A1, A2, A3);
B — increased accuracy (B1);
B — the usual accuracy (В1, В2, В3, В4, В5).
A circle of steel is produced in rods.
In accordance with the order, a steel circle is manufactured:
A multiple of the measured length;
(It is possible to meet additional requirements for the quality of rolled products and the quality of steel).
The steel circle is manufactured in length:
From 2 to 6 m — a circle of carbonaceous quality and a circle of low-alloy steel;
From 2 to 6 m — a circle of high-quality carbon and a circle of alloy steel;
From 1,0 to 6 m — a circle of high-alloy steel.
Limit deviations along the length of rolled metric and multiple dimensional length should not exceed:
+30 mm — with a length of up to 4 m inclusive;
+50 mm — for a length exceeding 4 m up to 6 m inclusive.
+70 mm — for a length exceeding 6 m.
In addition, the production of wire in coils, as well as sheet products in the form of sheets and strips is envisaged. The standard provides the following assortment of rolled metal:
Buy the rolled steel spring steel of all brands and profiles at affordable prices offers the company Elektrovek-steel. The supplier guarantees the timely delivery of products to the address specified by the customer.
