Flange materials acc. to ASTM. The material qualities for these flanges are defined in the ASTM standards. These ASTM standards, define the specific manufacturing process of the material and determine the exact chemical composition of pipes, fittings and flanges, through percentages of the permitted quantities of carbon, magnesium, nickel, etc., and are indicated by "Grade".

Database Normal Forms1NF (First Normal Form) RulesWhat Is Composite Key?2NF (Second Normal Form) RulesWhat Are Transitive Functional dependencies?3NF (Third Normal Form) RulesThe Theory of Data Normalization in SQL is still being developed further. For example, there are discussions even on 6th Normal Form. However, in most practical applications, normalization achieves its best in 3rd Normal Form. The evolution of Normalization theories is illustrated below- Here you see Movies Rented column has multiple values.Now let's move into 1st Normal Forms:Heat Treatment Processes:Types, Methods, Purposes
What Is Heat Treatment?Types of Heat Treatment ProcessesTypes of Heat TreatmentPurpose of Heat Treatment of SteelHeat treatmentis defined as an operation involving the heating and cooling of a metal or an alloy in the solid-state to obtain certain desirable properties without change composition. The process of heat treatment is carried out to change the grain size, to modify the structure of the material and to relive the stresses set up the material after hot or cold working. 1. The heat treatment is done to improve the machinability. 2. To improve magnetic and electrical properties. 3. To increase resistance to wear, heat Normalization in DBMS:1NF, 2NF, 3NF and BCNF in Database
Anomalies in DBMSNormalizationFirst Normal FormSecond Normal FormThird Normal FormBoyce Codd Normal FormThere are three types of anomalies that occur when the database is not normalized. These are Insertion, update and deletion anomaly. Lets take an example to understand this.Example:Suppose a manufacturing company stores the employee details in a table named employee that has four attributes:emp_id for storing employees id, emp_name for storing employees name, emp_address for storing employees address and emp_dept for storing the department details in which the employee works. At The Basics of Database Normalization - LifewireApr 12, 2020 · What Is Normalization? Normalization is the process of efficiently organizing data in a database. There are two goals of the normalization process:eliminating redundant data (for example, storing the same data in more than one table) and ensuring data dependencies make sense (only storing related data in a table). Both of these are worthy goals, as they reduce the amount of space a
Whats the Difference Between Hot and Cold Rolled Steel There are many types of steel out there, with various shapes, grades, specifications, finishes, and other processing considerations. One key distinction among prefabricated steel products is the Normalizing Heat Treatment, Basic Steel & Metal Normalizing Heat Treatment process is heating a steel above the critical temperature, holding for a period of time long enough for transformation to occur, and air cooling. Normalized heat treatment establishes a more uniform carbide size and distribution which facilitates later heat treatment operations and produces a more uniform final product.
