Hi, Welcome to factory !
ASTM specifications represent a consensus among producers, specifiers, fabricators, and users of steel mill products. ASTMs designation system for metals consists of a letter A for ferrous materials followed by an arbitrary sequentially assigned number. These designations often apply to specific products, for example A548 is applicable to ...
The first letter or symbol identifies the producing mill. The next marking is the bar size. The third marking symbol designates the type of reinforcing steel usually either S for carbon-steel ASTM A615 or W for low-alloy steel ASTM A706.
ASTMs steel standards are instrumental in classifying, evaluating, and specifying the material, chemical, mechanical, and metallurgical properties of the different types of steels, which are primarily used in the production of mechanical components, industrial parts, and construction elements, as well as other accessories related to them.
Apr 28, 2017 The heat-treatment designations and microstructure nomenclatures for many structural metallic alloys were established for traditional metals processing, such as casting, hot rolling or forging. These terms do not necessarily apply for additively manufactured i.e., three-dimensionally printed or 3D printed metallic structures. The heat-treatment terminology for titanium alloys generally ...

Jun 17, 2014 There are a lot of steel standards, there are tens of thousands of steel grades. As a stockist of heavy carbon steel plates these are the 40 key EN steel standards that we tend to use most often.. An EN Steel standard is a European standard or euro norm that specifies the requirements for a product or process.

Standard taps are either standard coarse series threads NC 14-20, fine series threads NF 14-28 or extra fine series NEF 14-32. There are other standard tap designations such as NPT or NPTF for tapered pipe threads. Special taps are usually designated NS, indicating a special thread size.

Dec 21, 2010 Abstract. After the intentional release of Bacillus anthracis through the U.S. Postal Service in the fall of 2001, many environments were contaminated with B. anthracis spores, and frequent inquiries were made regarding the science of destroying these spores. We conducted a survey of the literature that had potential application to the inactivation of B. anthracis spores.

designations include -processing, -processing, -annealing, duplex annealing and mill annealing. Owing to the absence of a thermomechanical processing step, these traditional designations can pose a problem when titanium alloys are first produced via additive manufacturing, and then heat-treated. This
