time quenching, n–interrupted quenching during which the duration of holding in the quenching medium is controlled. transformation ranges, n–these ranges of temperature inside which austenite types during heating and transforms throughout cooling. snap temper, n–a precautionary interim stress-relieving treatment applied to a high-hardenability metal instantly after quenching to prevent cracking because of delay in tempering it at the prescribed greater temperature. solution heat remedy, n–heating a steel object to a suitable temperature, holding it at that temperature long sufficient to trigger a number of constituents to enter into strong answer, after which cooling it rapidly enough to hold such constituents in answer. spheroidizing, n–heating and cooling a metal object to supply a spheroidal or globular form of carbide in its microstructure. DISCUSSION–Unlike burning, it may be attainable to revive the unique properties/microstructure by additional heat therapy or mechanical working, or a mix thereof. heat therapy, n–heating and cooling a steel object in such a method as to acquire desired conditions or properties.

A superscript epsilon indicates an editorial change because the final revision or reapproval. This standard has been accredited to be used by businesses of the Department of Defense. ASTM International takes no position respecting the validity of any patent rights asserted in connection with any item talked about in this commonplace. Users of this normal are expressly suggested that determination of the validity of any such patent rights, and the risk of infringement of such rights, are entirely their own accountability.

These variations could also be important to at least one consumer, but not significant to a different consumer. Therefore, this handbook makes use of the time period comparative to indicate related requirements which have been compared to one another. Comparative is a relative word that is inevitably dependent upon the top consumer’s requirements, who is ultimately answerable for selecting the appropriate metal for a particular utility.

S620QL1

S620Q, S620QL, EN 10025-6 S620QL1 steel plate heat treatment process (quenching and tempering)

 

1. S620 steel plate is a quenched and tempered high-strength steel plate. The series grades are S620Q, S620QL, and EN 10025-6 S620QL1. It is a low-carbon non-alloy structural steel plate of European standard EN10025-6.
Domestic Gang Iron and Steel Company can produce it.
In order to ensure its performance, this type of steel plate has a carbon content below 0.2%.

2. S620Q, S620QL, EN 10025-6 S620QL1 steel plates, where S means structural steel, and Q means that the impact temperature of the steel plate is -20°C,

 

Then QL means that the impact temperature of the steel plate is -50°C. Then guess what QL1 represents. QL1 means that the impact temperature of the steel plate is -60°C. 620 means that the thickness of the steel plate is £50mm. The minimum yield strength value is specified.

 

3. The steel specified in this standard can be used for the production of hot-rolled plates with steel grades S460, S500, S550, S620, S690, S890, and S960 series steel plates with a minimum nominal thickness of 3mm and a maximum nominal thickness of ≤150mm. After quenching and tempering
The specified minimum yield strength of steel is 460MPa1) to 960 MPa1)

4. Steel grades and varieties

 

The standard specifies 7 steel grades, and they have different yield strengths under ambient temperature conditions.
When required, all supplied steel grades from the following varieties shall be specified.
The minimum value specified for impact energy when the temperature is not lower than -20°C (no mark).
When the temperature is not lower than -50℃, the specified minimum value of impact energy is represented by L.
(Except for S960) The minimum specified impact energy when the temperature is not lower than -60℃ is represented by L1.
In quenching and tempering delivery conditions (Q) and grade L: steel EN 10025-6-S460QL; or steel EN10025-6-1.8906.

 

5. Delivery conditions of S620Q, S620QL, EN 10025-6 S620QL1 steel plate

 

Quenching + tempering (Q).
Note: Quenching and then tempering directly after hot rolling is considered equivalent to conventional quenching and tempering.

 

6. Impact performance of S620Q, S620QL, EN 10025-6 S620QL1 steel plate

 

S620Q at -20℃; S620QL at -50℃; EN 10025-6 S620QL1 at -60℃
