15F
Characteristics of 15F:
The strength, hardness, and plasticity of 15F steel are similar to those of 10/10F steel. To improve its cutting performance, it is necessary to perform normalizing or water toughening treatment to appropriately increase its hardness, ligament properties, good weldability, and low hardenability and hardenability
Usage of 15F:
15F steel is used for small and medium-sized structural components with low stress, simple switching, but high toughness requirements or good welding performance, as well as carburized parts, mechanical fasteners, die forgings, and low load parts that do not require heat treatment, such as bolts, screws, flanges, chemical machinery storage tanks, steam boilers, etc
Applicable scope of 15F:
Used for manufacturing carburized parts, fastening parts, and low load parts that do not require heat treatment for mechanical components, such as screws, bolts, flanges, etc.
15F mechanical properties:
Tensile strength σ b (MPa): ≥ 355 (36)
Elongation rate δ 5 (%): ≥ 29
Shrinkage rate of cross-section (%): ≥ 55
Chemical composition of 15F steel:
Carbon (C) 0.12-0.19,
Chromium (Cr) ≤ 0.25,
Manganese (Mn) 0.25-0.50,
Nickel (Ni) ≤ 0.25,
Silicon (Si) ≤ 0.07,
Phosphorus (P) ≤ 0.035,
Sulfur (S) ≤ 0.035,
Copper (Cu) ≤ 0.25
