Steel Forging Knowledge and News

Proper corrosion-resistant stainless steel selection is not simply about choosing the most expensive grade. It requires comprehensive judgment based on the medium, chloride ion concentration, temperature, welding requirements, and budget. Only by understanding the principle of the stainless steel passive film and referring to real application cases in the same industry can you select the right corrosion-resistant stainless steel, extend equipment service life, and reduce long-term operation and maintenance costs. If you have a specific working condition, you can provide the medium, temperature, and chloride ion parameters so that a suitable corrosion-resistant stainless steel grade can be evaluated.

In manufacturing, molds are often called the "mother of industry," and mold steel is the core material that determines mold life, precision, production efficiency, and cost. Whether it is mobile phone housings, automotive lamp covers, medical containers, optical lenses, or stamped, die-cast, and for

D2 tool steel is a high-carbon, high-chromium, air-hardening cold-work tool steel widely used in dies, stamping, cutting, and wear-resistant tooling. With roughly 1.5% C, 12% Cr, 1% Mo, and 1% V, D2 reaches 60–62 HRC and delivers excellent wear resistance and dimensional stability, making it a default choice for blanking dies, forming rolls, slitting knives, thread rolling dies, and wear plates. This article explains what D2 steel is, how it is classified under AISI/ASTM A681, and how it compares with A2 steel. A2 is tougher but less wear-resistant; D2 is preferred when abrasive wear dominates, while A2 suits punches and tools subject to impact. The article also maps D2 steel equivalents across global standards, including DIN 1.2379, EN X153CrMoV12, JIS SKD11, GB Cr12Mo1V1, and UNS T30402, helping buyers verify specifications from international D2 tool steel suppliers.

If you work in die casting, hot forging, or extrusion, you have almost certainly encountered H13 tool steel. It is the workhorse of hot-work tooling — the material that endures molten aluminum at 700 °C, the hammering of a forging press, and the relentless thermal cycling of high-pressure die castin

Against the backdrop of continuously increasing investment in oil and gas exploration and development, manufacturers of oil wellhead equipment and drilling tools are facing an increasingly acute contradiction: downstream demand growth is clear, while upstream forging supply frequently falls short. I
