Supply of free cutting iron SAE1215 hexagonal bar cold drawn hexagonal steel

SAE1215 hexagonal bar is a metal rod with a hexagonal cross-sectional shape. SAE1215 material belongs to free cutting steel.

Main characteristics of SAE1215 hexagonal bar:

1. Good cutting performance: With a high sulfur content, it can promote the formation of small and short curled radii of chips during cutting, which are easy to eliminate, reduce tool wear, lower surface roughness, and improve tool life;

2. High strength and plasticity: able to meet the usage requirements of various parts;

3. High material utilization rate: The cold drawing process results in minimal loss of raw materials, which can save a lot of materials and time compared to traditional lathe machining. Especially when the amount of materials used is large, the cost saving effect is significant;

4. Environmental characteristics: Compared with 12L14, it does not contain lead or harmful substances to the environment, which meets environmental requirements.

Application areas:

Mechanical manufacturing: used for manufacturing components such as shafts, gears, bolts, nuts, etc. in various types of mechanical equipment such as woodworking machinery, ceramic machinery, papermaking machinery, glass machinery, food machinery, construction machinery, plastic machinery, textile machinery, etc.

Automotive industry: suitable for manufacturing small parts on automobiles and motorcycles, such as engine components, brake system components, fasteners, etc., with strict requirements for dimensional accuracy and smoothness, but relatively low requirements for mechanical performance of standard parts.

Electrical products: can be used to manufacture components of electrical products such as motor shafts, fan shafts, sewing machine shafts, etc.

Furniture manufacturing: especially for exporting metal furniture such as coffee tables, chairs, outdoor furniture frames and connecting components.

Hardware products: used for producing various small hardware accessories, such as guide rails, machine keys, nuts, screws, round nails, hexagonal nails, octagonal nails, and various standard parts of different specifications.

How to choose a suitable steel rod when making springs：

1, look at the material:

High carbon steel: with high hardness and wear resistance, suitable for mining, construction and other high wear environment;

Alloy steel: Added alloy elements on the basis of carbon steel, improve the strength and wear resistance, suitable for high-load, high-wear working environment;

Stainless steel: has a corrosion resistance and wear resistance, suitable for harsh environments, while having a beautiful appearance.

2, look at the specifications and sizes:

Ensure that the diameter, length, roundness and other dimensions of the steel rod meet the standard requirements.

3, look at the surface quality:

Select steel rods with smooth surfaces, no cracks and no folding to ensure good surface quality.

4, look at the mechanical properties:

Select steel rods that meet the mechanical properties requirements according to the needs to ensure that their strength and toughness meet the requirements of use.

5, different materials of steel rod application scenarios:

High carbon steel: suitable for mining, construction and other high wear environment.

alloy steel ‌ : suitable for high load, high wear working environment, such as crusher, screen and other equipment wear-resistant parts.

stainless steel ‌ : suitable for corrosion resistance and aesthetic requirements of higher occasions, such as gears, bearings and other mechanical parts ‌.
