FAQ
What is the difference between S690Q and S690QL?
S690Q: Minimum impact toughness tested at -20°C (30J average). → Typical Use: Cranes in temperate climates, quarry equipment. S690QL: Certified for -40°C and below (≥40J impact toughness). → Critical Use: Arctic pipelines, offshore platforms, mining vehicles in Siberia.
What grade is S690QL material?
S690QL is a high strength quenched and tempered steel grade that complies to steel specification EN 10025. The designation S690QL refers to a minimum yield strength of 690 MPa.
What is S690 grade steel?
S690 high yield & fine grain steel plate is a high strength, quenched and tempered fine-grain structural steel. Structural steel S690 is used in structures that must withstand very heavy loads. This grade is meant for structures where weight savings is important.
What is the equivalent of S690 steel?
Approximate equivalents
ASTM A514, EN 10149-2 Grade S700MC, AS/NZS 3579 Grade 700, AM 700, Bisalloy 80.
What is the price of S690QL material?
S690QL High Strength Steel Plates, Thickness: 5mm to 150mm at 5,600-13,500 CNY per tonne (approx. 5.6-13.5 CNY per kilogram)/440-900 USD per tonne (approx. 0.44-0.90 USD per kilogram)
What is the hardness of S690 QL steel?
S690QL steel stockholders and suppliers. S690QL is a quenched and tempered high strength steel supplied in full plates or cut pieces with delivery to the whole of the UK. With its high yield of minimum 690MPa it offers better strength than standard carbon steel grades.
What is the effective use of high strength S690 steel in construction?
The high strength S690 steels have an excellent strength-to-self-weight ratio, and they are highly efficient to be used in heavily loaded structures. Typical applications include piles and columns in buildings and supporting members in bridges.
What is the difference between S890QL and S690QL?
S690QL, S890QL, and S960QL are all water quenched and tempered steels that comply with the EN10025:6:2004 specification. These ultra high strength steels have a minimum yield strength of 690 MPa, 890 MPa, and 960 Mpa respectively, making them ideal for use in the haulage sector.
What is the difference between S700MC and S690ql?
The S700MC Steel is basically a structural steel plate developed especially for applications requiring high yield strength. They are used for several load bearing applications. The S690ql is a low alloy structural steel which is high in strength and comes with good weldability.
What is the yield strength of s690 steel?
690 MPa.
Yield strength of 690 MPa. Used in structures bearing extremely heavy loads, such as bridges, offshore drilling rigs and buildings, as well as in heavy construction equipment and cranes.
