DILLIMAX 1100 Processing
Keseluruhan teknik pemprosesan dan penggunaan adalah penting untuk kebolehpercayaan produk yang diperbuat daripada keluli ini. Pengguna harus memastikan reka bentuk, pembinaan dan kaedah pemprosesannya sejajar dengan bahan, sesuai dengan teknologi terkini yang perlu dipatuhi oleh fabrikasi dan sesuai untuk kegunaan yang dimaksudkan. Pelanggan bertanggungjawab untuk pemilihan bahan. Pengesyoran EN 1011 (Kimpalan) dan CEN/TR 10347 (Pembentukan) serta pengesyoran berkenaan keselamatan kerja mengikut peraturan negara harus dipatuhi.
We recommend to consult us prior to the first working with DILLIMAX 1100. Detailed instructions for flame cutting, welding, machining and about the structural properties of the DILLIMAX are provided in the technical information “MAKE SAVINGS WITH HIGH STRENGTH STEELS – DILLIMAX”.
DILLIMAX 1100 Cold forming
DILLIMAX 1100 can be cold formed below 200 °C (390 °F)5) taking into account its high yield strength. Flame cut or sheared edges in the bending area should be ground before cold forming. It is also advisable to round the plate edge slightly on the outside of the bend coming under tension stress during bending.
Cold forming is always related to a hardening of the steel and a decrease in toughness. In contrast to lower yield strength steels DILLIMAX 1100 can not be heat treated at temperatures about 550°C(1022 °F)5) to reduce the strain hardening effects.
After higher cold forming amounts or if prescribed by regulations, a new quenching and tempering treatment may become necessary to restore the required mechanical properties. In this case, we recommend to consult us prior to ordering.
Semasa pemprosesan, langkah-langkah keselamatan yang perlu perlu diambil, supaya tiada siapa yang akan terdedah kepada bahaya oleh kemungkinan keretakan bahan kerja semasa proses pembentukan.
Geometri berikut biasanya boleh dicapai dengan pembentukan sejuk tanpa pembentukan kecacatan permukaan (di mana t ialah ketebalan plat):
| Jejari lenturan minimum | Lebar die minimum | |||

| Arah melintang | 4 t | 5 t | 12 t | 14 t |
| Arah membujur | 5 t | 6 t | 14 t | 16 t |

Hot forming
If the temperature of 220 °C (428 °F)5) is exceeded, the initial tempering will be altered so that the mechanical properties are affected. To regain the initial properties new quenching and tempering become necessary. However, water quenching of a formed work piece or component will often be less effective than the original quenching in the plate mill so that the fabricator may not be able to reestablish the properties required. Therefore hot forming is not suitable.
Akhir sekali, adalah menjadi tanggungjawab fabrikasi untuk mendapatkan nilai keluli yang diperlukan melalui rawatan haba yang sesuai.
Pemotongan api dan kimpalan
Due to its high yield strength, DILLIMAX 1100 requires special care during plate processing.
For flame cutting, the following minimum preheating temperatures are recommended: 75 °C (165 °F)5) for plate thickness up to 20 mm (0.8 in)5) and 125 °C (260 °F) 5) for plates thickness up to 40 mm
(1.6 in)5).
For general welding instructions, please consult the EN 1011-2. So far no welding consumables are available that produce tensile properties matching the base material. Thus, fully loaded joints must be avoided by an appropriate design. Minimum preheating, interpass and working temperature shall be limited to a range from 150 °C (302 °F)5) up to 200 °C (390 °F)5).
To avoid hydrogen-induced cold cracking, only filler materials which add very little hydrogen to the base metal may be used. Therefore, shielded arc welding should be preferred.
For manual arc welding, electrodes with basic coating (type HD < 5 ml / 100 g in accordance with ISO 3690), and dried according to the manufacturer’s instructions, should be used.

With increasing plate thickness, increasing hydrogen charge and restraint of the weld, a soaking for hydrogen effusion immediately after welding is recommended. The temperature for this treatment shall be in the range of 180 °C (355 °F)6) up to 220 °C (428 °F)6). To reduce hydrogen to an uncritical rate, we recommend the following holding times in the temperature range of 180 °C (355 °F)6) up to 220 °C (428 °F)6) (1 hour for welding joint thickness of up to 20 mm (0.8 in)6); 2 hours for welding joint thickness of up to 30 mm (1.18 in)6); and 4 hours for welding joint thickness of up to 40mm (1.6 in)6)).
A stress relief heat treatment is not possible and flame straightening is generally not permitted because these operations would reduce the tensile properties of the steel. Only in areas of the component where a local softening can be tolerated, straightening by flame or by inductive heating may be applied (in agreement with the design department).
