Features of Alloy Steel Plate

Alloy Steel Plate offered by us has some of the outstanding features which makes it a preferred choice.
● Corrosion Resistant Surface
● High Strength
● Excellent Durability
● Excellent Tensile Strength
● Excellent Hardness

Application of Alloy Steel Plate

Alloy structural steel with suitable hardenability, after appropriate metal heat treatment, the micro structure is homogeneous sorbite, bainite or very fine pear lite, thus has higher tensile strength and showed (around 0.85), high toughness and fatigue strength, and low ductile to brittle transition temperature, can be used in the manufacture of section size larger machine parts.

Jindalai exports Alloy Steel Plate to Saudi Arabia, UAE, Bahrain, Peru, Nigeria, Jordan, Muscat, Kuwait, Dubai, Thailand (Bangkok), Venezuela, Germany, Canada, Russia, Australia, Vietnam, Kazaksthan, Jiddah, Libya, Yemen, Algeria, Qatar, Oman, Iran etc.
