What is the difference between S690QL and ASTM A514?

S690QL and ASTM A514 are both quenched and tempered, high-strength steel plates, but their primary difference lies in their standards and properties. S690QL is a European standard with a minimum yield strength of 690 MPa, while ASTM A514 is a US standard that typically has a minimum yield strength of 100 ksi (approximately 690 MPa) but comes in different grades with varying properties. S690QL is known for its high tensile and yield strength, whereas ASTM A514 is noted for its weldability, toughness, and resistance to brittle fracture, with different grades offering specific benefits.

S690 QL is a high yield structural steel grade produced in compliance with EN 10025:6:2004. The material is heat treated using the quench and temper process and has good bending and welding properties.
Due to the materials high strength nature, using S690QL will promote leaner designed structures with increased payload capacity and energy efficiency.

What is A514 steel plate?

A514 material is known for its high yield strength, weldability, and toughness even at low temperatures. A514 Steel Plates are made up of this material. Astm A514 Plate Suppliers recommend this as it is a low carbon quenched and tempered alloy steel. It is a high performing material at a low cost for structural use and to be used in high wear machine applications. a514 t1 also provides resistance to corrosion, and impact abrasion. ASTM a514 grades are usually used in earth moving equipment frames, truck frames and bodies, building and bridge frames, and so on

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.

What is the ASTM A514 standard?

The ASTM A514 specification is the Standard Specification for High-Yield-Strength, Quenched and Tempered Alloy Steel Plate, Suitable for Welding used in applications where Yield Strengths of ≥ 100 ksi are required for plates up to 2-1/2" thick, inclusive.

What is equivalent to ASTM A514?

A514/T-1 Equivalent Grades
For projects requiring EN standard materials, EN S700 or EN690 may be possible alternatives to A514, depending on project requirements. Other Q&T steel plate grades have similar properties to A514 plate and may be suitable for use high wear and stress applications.

Is A514 the same as A36?

A514 has much higher yield strength (100 ksi vs. 36 ksi) and is alloyed for toughness, while A36 is milder and cheaper. Can A514 replace A36? Yes, in applications needing higher strength, but it costs more and requires different welding procedures.

What is the difference between A514 and A572 steel?

A572 is a low-carbon steel with good weldability and moderate strength, commonly used in structural applications. A514 is a high-strength, quenched, and tempered alloy steel primarily used in heavy-duty construction and mining equipment due to its exceptional strength and toughness properties.
