316L Stainless Steel fabricated via laser powder bed fusion microstructure with a light electro-etch to reveal meltpool track boundaries as seen using SEM.

Hi everyone The classification of stainless steels is based on its microscopic structure. The first step after examining the microstructure is to examine the chemical composition of stainless steels. The chart is based on the percentage of carbon, nickel and chromium, and it can be used to understand that stainless steel is Which family of stainless steels (martensitic, ferritic, duplex, austenitic and precipitation hardening) is to help us... #stainless_steel #steel #metallurgy #materials_engineering #classification #chemical_composition #new_project #industry #technology

Beryllium is a light and rare metal with a small atomic number and low density (only 1.847g/cm³), about 2/3 of aluminum and 1/2 of titanium. High melting b point (1283℃). Beryllium is α-Be at room temperature and has a dense hexagonal structure. The phase transition occurs at 1254 ° C and the structure is β-Be. Beryllium has the greatest heat capacity of all metals. With a specific heat capacity of 1.8828 J/gK at room temperature, beryllium absorbs more heat than other metals, and this property is maintained until the melting point. The thermal conductivity of beryllium at room temperature is 0.15kW/(m.K). The thermal expansion coefficient of beryllium is comparable to that of stainless steel and Ni-Co alloy. The thermal diffusion performance is also very good. Beryllium has a reflectance of 50% to visible light, 55% to ultraviolet light, and 98% to infrared (10.6m). It has a high penetration rate (almost transparent) to X-rays, about 17 times that of aluminum, and is an indispensable material for X-ray Windows. The elastic modulus of beryllium is very high (309,000 MPa), about 4 times that of aluminum, 2.5 times that of titanium, and 1.5 times that of steel. Especially in the temperature range from room temperature to 615 ° C, the specific stiffness is about 6 times that of steel, aluminum, and titanium. In addition, the thermal neutron absorption rate of beryllium is the smallest among all metals, while the scattering cross section is large. In addition, beryllium is a steel grey metal light metal. Beryllium is harder than its peers, unlike calcium, strontium, and barium, which can be cut with a knife.

Magnetic Properties of Carbon Steels and Common Stainless Steel Grades   Did you know that while most carbon steels are magnetic, it’s not true for all of them? However, due to their structure, almost all carbon steels commonly used in industrial and construction applications tend to be magnetic. Carbon steels are magnetic mainly because of their crystal structures. In ferrite (which has a BCC structure) and martensite (with a BCT structure), the way the iron atoms are arranged allows for magnetism. On the other hand, austenitic structures can disrupt this magnetism, making them non-magnetic. Here’s a table that shows different types of carbon steels and stainless steels, their magnetic properties, structures, and common grades. Understanding these characteristics not only aids in making informed decisions in material selection but also opens doors for innovative applications across various industries. #SteelIndustry #SteelProduction #Metallurgy #MaterialEngineering #Metals #Manufacturing #IndustrialSteel #StructuralSteel

Martensitic steels are a category of stainless steels known for their high strength, hardness, and wear resistance. The martensitic microstructure is achieved through heat treatment, specifically quenching and tempering. This process transforms the steel's crystal structure, resulting in a hard, martensitic phase. These steels are magnetic and exhibit excellent mechanical properties, making them suitable for applications such as knives, turbine blades, surgical instruments, and certain industrial equipment. Ferritic-Martensitic steels, also known as duplex or martensitic duplex steels, combine characteristics of both ferritic and martensitic stainless steels. This dual-phase microstructure enhances the overall performance of the steel. Ferritic-Martensitic steels offer good corrosion resistance, high strength, and toughness.
