Gangsteel supply EN10025-6 s550ql and EN10027-1 s550ql and EN10027-2 1.8926 steel . thickness 3mm to 180mm.Heat treatment of S550QL steel : Quenching and tempering (Q+T) S550QL is a European standard special alloy structural steel, attributed to quenched and tempered high yield strength structural steel, S indicates structural steel, 550 is the yield value, unit MPa, Q indicates delivery
Conditions, L indicates that the temperature is not lower than -50��, the specified smaller value of impact energy, S550QL steel is a trademark in the EN 10025-6 specification, this specification rules that the smaller nominal thickness of the steel is 3mm, and the larger nominal thickness ≤

Unfortunately the metal on this case can also be very brittle and it’s not potential to make use of it in a lot of purposes. A method of warmth remedy for alleviating this drawback known as tempering and requires the quenched metal to be re-heated though this time to under the lower essential temperature. It have to be thought-about that increased heat enter results in lower tensile properties in the weld metallic. If a stress relieving heat therapy is planned all through or after plate processing, this could even be considered when deciding on the filler supplies. To keep away from hydrogen-induced chilly cracking, solely filler materials, which add very little hydrogen to the base metallic, may be used. This steel is utilized in completely different capabilities corresponding to heavy transportation, building industry, machine constructing EN S690QL1, and lifting instruments.

A 941 – 03 process annealing, n—within the sheet and wire industries, heating a steel object to a temperature near, but below, Ac1 after which cooling it, in order to soften it for additional cold working. progressive growing older, n—getting older by growing the temperature in steps, or repeatedly, during the growing older cycle. quench getting older, n—growing older related to quenching after solution warmth remedy. quench annealing, n—annealing an austenitic steel object by solution heat treatment.

They are established on the precept of consensus and adopted by the votes of weighted majority. Adopted requirements have to be applied of their entirety as national standards by each member country, whatever the way during which the national member voted, and any conflicting nationwide requirements must be withdrawn. The identification of European standards in every member nation begins with the reference letters of the nation’s nationwide requirements physique, for example, BS for BSI within the United Kingdom, DIN for DIN in Germany, NF for AFNOR in France, and so forth.

Table numbers ending in the letter A designate that it was the primary criterion used for comparability, whereas desk numbers ending with the letter B were “mirrored” from the A tables. In this manner, the user must first think about the information within the A desk, then see how nicely the info within the B desk match the steels which are being compared. For instance, ASTM A 958 Grade SC 4330 has one chemical composition, but has thirteen completely different energy lessons based mostly on heat therapy . So just because two metal grades have comparative chemical compositions does not mean that they are comparable in mechanical properties, and vice versa. Using data found in this handbook is just one step in finding appropriate comparable steel for the meant application. With this basic methodology in place, the next is a list of the comparison rules that had been established to provide this handbook.

pure aging, n—spontaneous getting older of a brilliant-saturated solid solution at room temperature. nitriding, n—introducing nitrogen right into a solid metal object by holding it at a suitable temperature in touch with a nitrogenous surroundings. normalizing, n—heating a metal object to a suitable temperature above the transformation range and then cooling it in air to a temperature considerably below the transformation vary. overaging, n—aging under circumstances of time and temperature larger than these required to obtain most change in a certain property, in order that the property is altered away from the maximum. overheating, n—heating a steel object to such a excessive temperature that excessive grain growth occurs. DISCUSSION—Unlike burning, it might be attainable to restore the unique properties/microstructure by additional heat remedy or mechanical working, or a mix thereof.

EN S690QL1 is Alloy particular metal with specified minimal values of impression vitality at temperatures not decrease than -60 °C. Full info as to uses of metal cross ties is given in a separate pamphlet on Steel Cross Ties. SUMMARY OF CHANGES Committee A01 has recognized the location of selected modifications to this normal because the final issue (A 941 – 01) that will impression the usage of this standard. A 941 – 03 DISCUSSION—The two ranges are distinct, typically overlapping but by no means coinciding. The limiting temperatures of the ranges are dependent upon the steel composition and the rate of change of temperature, particularly during cooling. warmth treatment, n—heating and cooling a metal object in such a means as to obtain desired situations or properties. DISCUSSION—Heating for the only purpose of scorching working is excluded from the meaning of this definition.

What is different in EN10025-6 S550Q S550QL and S550QL1?

S550Q, S550QL, S550QL1 are European standard quenched and tempered high-strength structural steel plates.
S550Q, S550QL, S550QL1 organize production and implement European standard EN10025-6.
S550Q, S550QL, and S550QL1 conform to EN10029 standard for appearance quality deviation.
The main difference between S500, QS550QL and S550QL1 is low temperature impact toughness: Q means -20℃ impact; QL means -40℃ impact; QL1 means -50℃.
