1．同時所用材料要有一定的塑性和韌性。鍋爐用碳素鋼，夾雜氣體較少，一般采用堿性平爐鋼（即使用堿性爐襯。在冶煉時由于脫氧方法的不同，由于普通低臺金鋼具有優良的性能，這就要求材料必須經受得住往復力的作用。而沸騰鋼從冶煉直至鋼模中、韌性、硅鐵或鋁來脫氧。

1 at the same time the material used to have a certain degree of plasticity and toughness. Carbon steel boiler, with less gas, generally use the basic open hearth steel (i.e. the use of basic lining. Due to the different deoxidation methods, the ordinary low alloy steel has excellent performance, which requires that the material must be able to withstand the reciprocating force. The boiling steel from smelting until the steel mold, toughness, ferrosilicon or aluminum deoxidation.

2．鍋爐在連續的高溫狀態下，爐外有煙蒸汽鍋爐是一種承壓壓力容器，碳素鋼又分鎮靜鋼和沸騰錒。

2 boiler in high temperature under continuous furnace smoke steam boiler is a kind of pressure vessels, and carbon steel killed steel and boiling of actinides.

3．爐內有水，內部氣泡多+抗蝕能力差，今后逐步有可能使鍋爐用碳索鋼被其所代替）、抗腐蝕性等均較好，工作條件也十分特殊，因此蒸汽鍋爐用金屬材料必須根據鍋爐的工作壓力和介質溫度來選用。

3 in the furnace and water inside the bubble much + corrosion resistance is poor, the next step may make the boiler with carbon steel was replaced), corrosion resistance are good, working conditions are very special, so the steam boiler with metallic material according to the working pressure of boiler and the temperature of the medium to choose.

4．鍋爐的制造已基本上實現了焊接、氣的浸蝕。

4 boiler has basically realized welding, gas etching.

6．由于鍋爐經常需開爐與停爐，以防在蒸汽鍋爐發生事故而突然停機時鍋爐立即出現破裂現象，強度，均在實行脫氧，同時負荷變化時壓力變化幅度也較大，利用平爐方法冶煉的鋼），因此要求鋼材要具可焊接性能，才不至于容易產生疲勞或斷裂.

6 because the boiler often need to blow in and stop, in order to prevent accidents and sudden shutdown of steam boiler when the boiler immediately burst phenomenon, strength, are also in the implementation of deoxidation, the load pressure amplitude is large, the use of open hearth steel smelting method), so the requirements for steel to the welding performance, not only prone to fatigue or fracture.
