Q690C carbon steel plate sheet material vs stainless steel

The ASTM/ASME SA516 Q690C carbon steel plate sheet specification covers carbon steel plates, which are mainly used for welding pressure vessels, where improving notch toughness is very important. The Q690C carbon steel plate sheet tensile strength range is 55-90MPa, and its versatility makes this specification very popular in applications.

Our company is a large Q690C carbon steel plate sheet steel enterprise integrating steel plate production, sales and processing. It is a first-class agent of Shanxi Taigang, Shanghai Baosteel, Jiugang, Xi'an Huaxin, Taishan steel, Dongfang special Q690C carbon steel plate sheet steel and southwest special steel. It is a special dealer of famous steel plants in China, such as Columbus, NAS, acerinox, Outokumpu, Arcelor, nipponmetalindustry, nipponyakinkogyo, NSC, etc.

Tempering includes high temperature tempering, medium temperature tempering and low temperature tempering. Tempering means to reheat the Q690C carbon steel plate sheet quenched steel to a certain temperature and then cool it in a certain way. Tempering can reduce or eliminate the internal stress produced by quenching, reduce the hardness and strength, and improve the ductility or toughness of steel. After Q690C carbon steel plate sheet quenching, the workpiece should be tempered in time, and the required mechanical properties can be obtained through the combination of quenching and tempering.

Manganese is used to deoxidize and remove sulfur in steel when making steel. It is an beneficial element in Q690C carbon steel plate sheet steel. Manganese has a strong ability to deoxidize and remove sulfur, it can eliminate or reduce the hot brittleness caused by oxygen and sulfur, and improve the strength and hardness of Q690C carbon steel plate sheet steel.

We should help solve the customer's problems in time, not just verbally, without solving the problems or shirking the responsibility. Improving after-sales efficiency can make customers feel respect. We should take their problems seriously and show sincerity. It can also give customers a good impression and reduce the negative impact.
