Production process

Description

Boiler vessel plate, used for manufacturing all kinds of boilers and important accessories, because the boiler steel plate in the medium temperature (below 350°C)
under high pressure working, in addition to withstand higher pressure, but also subjected to impact, fatigue load and water and gas corrosion, the requirement to ensure a certain strength, but also have good welding and
cold bending performance.It is China's most widely used, the largest amount of pressure vessel special steel plate.

Manufacturing methods

Steel is smelted in an oxygen converter or an electric furnace

The compression ratio of continuous casting billet is not less than 3

Folding Q345R

Q345R is a large type of steel plate - container plate

Marking method :Q345R 16MnR 16MnG.

For example: Q345R.Q-" qu "first letter of Pinyin.345- Yield strength value.R: The first letter of "rong" in Pinyin.

According to the new classification of GB 713-2008 Steel Plates for Boilers and Pressure Vessels implemented on 1 September 2008, 16Mng, 16MnR
and 19Mng are combined as Q345R.Q345R is the common low alloy steel, is the boiler pressure vessel common steel, delivery state: hot rolled or normalized, belongs to the low alloy steel.The performance is similar to that
of Q345(16Mn) (the yield strength of 16mm steel plate is greater than 345Mpa), the tensile strength is between (510-640), the elongation is greater than 21%, and the zero V-type impact energy is greater than 34J.Q345R Process
reference standard GB713-2008.

Q345R steel is a special plate for pressure vessel whose yield strength is 340MPa. It has good comprehensive mechanical properties and technological
properties.Phosphorus and sulfur content is slightly lower than low alloy high strength steel plate Q345(16Mn) steel, in addition to the tensile strength, elongation than Q345(16Mn) steel, also requires to ensure the impact
toughness.It is China's most widely used, the largest amount of pressure vessel special steel plate.

Q345R characteristics

Q345R steel plate is a special plate for pressure vessel whose yield strength is 265-345mpa. It has good comprehensive mechanical properties
and technological properties.Phosphorus and sulfur content is slightly lower than low alloy high strength steel plate Q345(16Mn) steel, in addition to the tensile strength, elongation than Q345(16Mn) steel, also requires
to ensure the impact toughness.It is China's most widely used, the largest amount of pressure vessel special steel plate.

Folding Q245R

It is a kind of steel plate -- boiler plate. The marking method is: similar to Q345R, the marking of low-alloy and high-strength structural
steel is represented by the first letter of Chinese pinyin of yield strength value "qu" and pressure vessel "capacity".For example: Q245R.Q-" qu "first letter of Pinyin.245- Yield strength value.R:
The first letter of "rong" in Pinyin.

It has special components and properties

Mainly used for pressure vessels, according to the use, temperature, corrosion resistance, the container plate should be used, is not the same.

Delivery status: hot rolling, control rolling, normalizing.Additional flaw detection is made by agreement between the supplier and the supplier.

Such as :20R, 16MnR, 14Cr1MoR, 15CrMoR, 09MnNiDR, 12Cr2Mo1R, 16MnR(HIC), 20R(HIC) and so on

The above are commonly used brands in China;Foreign brands are also available, such as SA516Gr60, SA516GR70, etc.

Niobium, vanadium and titanium can be added to Q245R steel, and the content shall be filled in the quality certificate. The total content of
the above three elements shall be no more than 0.050% respectively
