How strong is HY-80?
80 ksi
HY 80 is a high yield steel with a minimum yield strength of 80 ksi. While many steels offer high yield strength, HY 80 also offers exceptionally high impact strength as well.
What is Hy steel?
HY 100 is a high yield steel with minimum yield strength of 100 ksi. While many steels offer high yield strength, HY 100 also offers exceptionally high impact strength as well. This combination makes HY 100 unique among steels. This material is used extensively in marine defense and petrochemical applications.
How hard is HY-80?
HY-80 is a high yield strength (minimum of 80 ksi) , low carbon, low alloy steel with nickel, molybdenum and chromium. It has excellent weldability and notch toughness along with good ductility even in welded sections. This alloy is best known for use in shipbuilding for welded hull plates and structural use.
What is NQ1 steel?
The pressure hull containment structure of the submarine is fabricated from high strength steel known as Naval Quality 1 (NQ1) to the highest standards.
Is HY-80 a carbon steel?
HY-80 steel is a member of the low carbon, low alloy family of steels with nickel, chromium and molybdenum (Ni-Cr-Mo) as alloying elements and is hardenable. The carbon content can range from 0.12 to 0.20 wt% with an overall alloy content of up to 8 wt%.
What kind of steel is used on submarines?
High-strength alloyed steel
High-strength alloyed steel is still the main material for submarines today, with 250–350 metres (820 to 1,148 feet) depth limit, which cannot be exceeded on a military submarine without sacrificing other characteristics. To exceed that limit, a few submarines were built with titanium hulls.
What is high strength steel plate?
High Strength Sheet Steels have higher strength properties along with improved formability, weldability and/or atmospheric corrosion resistance than normally obtained from conventional carbon sheet steels. These desirable properties are obtained through selected chemical composition and controlled mill processing.
Is Hy 80 carbon steel?
HY-80 steel is a member of the low carbon, low alloy family of steels with nickel, chromium and molybdenum (Ni-Cr-Mo) as alloying elements and is hardenable. The weldability of the steel is good, though it does come with a set of challenges due to the carbon and alloy content.
What steel is a submarine made of?
High-strength alloyed steel is still the main material for submarines today, with 250–350 metres (820 to 1,148 feet) depth limit, which cannot be exceeded on a military submarine without sacrificing other characteristics. To exceed that limit, a few submarines were built with titanium hulls.
What is the highest tensile strength steel?
Tungsten has the highest tensile strength of any pure metal – up to 500,000 psi at room temperature. Even at very high temperatures over 1,500°C, it has the highest tensile strength.
What is 80 ksi steel?
The higher the KSI the stronger the steel. Steel that’s 80 KSI has traditionally been called Grade E steel and steel that’s 33 KSI has been called Grade C steel. Whether you call it by the newer KSI rating name or older grade names, it’s how we refer to the “strength” of the decking that’s being used on a project.
How thick is the skin of a submarine?
The external hull, which actually forms the shape of submarine, is called the outer hull, casing or light hull. This term is especially appropriate for Russian submarine construction, where the light hull is usually made of steel that is only 2 to 4 millimetres thick, as it has the same pressure on both sides.
What is Hy 80 steel?
HY 80 is a high yield steel with a minimum yield strength of 80 ksi. While many steels offer high yield strength, HY 80 also offers exceptionally high impact strength as well. This combination makes HY 80 unique among steels.
What is the yield strength of HY-80?
HY-80 is accompanied by HY-100 and HY-130 with each of the 80, 100 and 130 referring to their yield strength in ksi (80,000 psi, 100,000 psi and 130,000 psi).
What is HY80 tubing?
HY is also available in ID/OD Tubing up to 22′ length. HY 80 is a high strength low alloy martensitic steel containing small additions of chromium and nickel to help with corrosion resistance and is supplied in the Type B condition bright finish.
What is the difference between HY-130 and HY-80?
HY-80 and HY-100 are both weldable grades; whereas, the HY-130 is generally considered unweldable. Modern steel manufacturing methods that can precisely control time/temperature during processing of HY steels has made the cost to manufacture more economical.
