P20 steel is an AISI (American Iron and Steel Institute) type, medium-alloy mold steel. It is commonly supplied in a prehardened condition, with hardness ranging from approximately 28 to 40 HRC, or around 300 HB, and is also known by DIN 1.2311. The primary uses are Plastic molds, Zinc die-casting dies, and Holder blocks.

Introduction: What is D2 Tool Steel and Why is Hardness Key? D2 tool steel is classified under the “D” group, representing high-carbon, high-chromium cold-work tool steels. It is widely applied for long-run dies due to its superior wear resistance, good dimensional stability, and moderate toughness. D2 is considered a popular and often the most important

Introduction D2 tool steel is a prominent high-carbon, high-chromium cold-work tool steel, widely recognized for its excellent wear resistance and dimensional stability. It is a standard against which other tool steels are often measured for abrasion resistance. D2 steel is primarily applied in long-run cold-work tooling such as blanking, cold forming, drawing, lamination, and thread

D2 tool steel is a high-carbon, high-chromium, air-hardening steel. Its hardness is affected by chemical composition, heat treatment parameters, and microstructural interactions. Here are the detailed factors affecting D2 tool steel hardness. Alloying elements in the composition The composition of D2 steel is1 Carbon (C) Chromium (Cr) Molybdenum (Mo) Vanadium (V) Manganese (Mn) Silicon (Si)

Hardness is a fundamentally critical property for tool steels, directly influencing their ability to perform effectively in diverse applications ranging from cutting and forming to shaping various materials. Without adequate hardness, a tool steel cannot withstand the substantial loads imposed upon it during service. One very important use of tool steel is for cutting or

O2 tool steel heat treatment is crucial to achieving optimal performance. O2 tool steel is an oil-quenched cold work tool steel with high hardness, high wear resistance, and minimal deformation during heat treatment. Compared to water-quenched steel, O2 steel exhibits better dimensional stability and higher toughness after complete quenching1. The equivalent grades of O2 tool

The objective of D6 tool steel heat treatment is to transform its annealed structure, consisting mainly of ferrite and alloy carbides, into a hardened and tempered martensitic structure. If heat treatment is not performed correctly, D6 steel may also exhibit poor performance. What is D6 tool steel? D6 tool steel is a high-carbon, high-chromium cold-work

Obróbka cieplna stali narzędziowej D3 ma kluczowe znaczenie dla uzyskania jej optymalnych właściwości i obejmuje szereg etapów: podgrzewanie wstępne, austenityzację, hartowanie i odpuszczanie. Proces ten ma na celu przekształcenie mikrostruktury stali w utwardzoną i odpuszczoną strukturę martenzytyczną z węglikami, które zapewniają pożądane właściwości narzędzia skrawającego. Czym jest stal narzędziowa D3? Stal narzędziowa D3 to…

Podobnie jak w przypadku wszystkich stali narzędziowych, obróbka cieplna stali narzędziowej L6 ma kluczowe znaczenie dla uzyskania najlepszych parametrów. Proces ten zazwyczaj obejmuje sekwencję nagrzewania wstępnego, austenityzowania (hartowania), hartowania i odpuszczania. Czym jest stal narzędziowa L6? L6 to niskostopowa stal narzędziowa specjalnego przeznaczenia. Skład stali L61 obejmuje: Nikiel działa jako pierwiastek stabilizujący austenit, przyczyniając się do rozpuszczania w roztworze stałym.

Today, we will discuss 420 stainless steel vs 316. Both types of steel are called stainless steel, but they have fundamental differences and are used in very different applications. We will explain the differences between the two from various perspectives. 420 stainless steel vs 316: Classification and Microstructure 420 stainless steel is a martensitic stainless
