The first use of nodular cast iron

The first use of nodular cast iron

Ball iron cast already was in almost all first industry get applying in some, the intensity with these some high demand, plasticity, endurance, wearability, be able to bear or endure severe
Heavy heat and mechanical concussion, high temperature resistant or nodular cast iron is microtherm, anti-corrosive and standard stability. Use a condition to satisfy these altering, nodular cast iron has a lot of brand, furnished a of mechanical function and physical function very broad program.

The cast of most nodular cast iron that is like regulation of place of ISO1083 of world Organization for Standardization, principal produce in order to be not alloy condition. Apparent, this program includes tensile strength to be more than 800 Newton / millimeter, outspread rate is the high strenth brand of 2% . Another the utmost is tall plasticity brand, its outspread rate is more than 17% , and corresponding intensity is inferior (lowest is 370 Newton / millimeter spoon. Intensity and outspread rate are not the only basis that the architect picks material, and the main function with conclusive other still includes to succumb modulus of elasticity, wearability and intensity, fatigue intensity, hardness and concussion function. Additional, be able to bear or endure corrode sex and fight oxidation and electromagnetism function about the architect perhaps be crucial point. To satisfy these special apply, research and development iron of a group of austenite balls, make be proud one Resis of Ni dies normally ball iron. These austenite ball iron, principal change with zinc, chromium and manganese alloy, and include the world the level.
