304HC Stainless steel

What is stainless steel 304HC？

304HC stainless steel wire is made of stainless steel as raw materials of all kinds of different specifications and types of silk products, which has good corrosion resistance, high cost performance. Stainless steel wire specification from 0.1 mm to 6.5mm, divided into soft, hard in two kinds of mode of production.

Some common applications include: Fastener Manufacturing: Used to produce bolts, screws, nuts, and other fasteners for construction, automobilių, aerospace, and marine industries due to its corrosion resistance and mechanical strength.

Equivalents of grade 304HC

Grade 304HC stainless steel, where “HC” likely refers to “high carbon,” is a variation of the standard 304 stainless steel with a higher carbon content. This increased carbon content in 304HC enhances its tensile and yield strength, making it suitable for applications where elevated temperatures are present. It’s a close equivalent to 304H, and may also be referred to as X5CrNi18-10 (EN standard) or UNS S30409.

Mechaninės savybės 

• Tensile Strength: Typically between 600 į 800 MPa, indicating the maximum stress the material can withstand while being stretched or pulled before breaking. It reflects its structural integrity and load-bearing capacity.
• Derlingumo stiprumas: Around 250 į 300 MPa, representing the stress level at which the material begins to deform plastically, indicating its ability to return to its original shape after deformation.
• Pailgėjimas: Typically ranging from 40% į 60%, demonstrating the material’s ability to stretch or elongate before rupture, crucial for applications requiring ductility and formability.
• Kietumas: Generally in the range of 85 į 95 HRB (Rockwell B Hardness) or 180 į 220 HV (Vickers Hardness), indicating its resistance to indentation or scratching, essential for assessing its wear resistance and machinability.
• Elastingumo modulis (Young’s Modulus): Approximately 193 GPa, representing the material’s stiffness or resistance to deformation under stress, crucial for understanding its behavior under load.
• Impact Strength: Usually not specified directly for cold heading wire, but it indirectly relates to the material’s toughness, which is influenced by its composition, microstructure, and processing conditions.
