1. Hoʻohana ka paipu kila i ka Q235B, ka paipu kila welded (GB / T 3092) a i ʻole ka paipu kila seamless (GB / T 8162).

2. Hana 'ia ka poepoe kila me ka No. 45 kila forgings e ku ana i ka "Technical Conditions for High-Quality Carbon Structural Steel" GB 699, a me ka ikaika hua 360N/mm2

3. Ua hana 'ia nā bolts ikaika ki'eki'e no ka pahu hakahaka me 40Cr kinai 'ia a me ka wela a me ka wela e like me "Nā Kūlana Kūlana Kūlana Ki'eki'e Carbon Structural Steel" GB/T 16939.

4. ʻO ka pāpale sila o ke poʻo cone i hanaʻia i ke kila Q235B, aʻo ke poʻo cone i hanaʻia i nā forgings.ʻO ke anawaena o loko o ka pahuHoʻohana ʻo M33 i ka Q355B.

5. Hana 'ia ka nut threadless me Q235B kila forgings.Ke ʻoi aku ke anawaena o nā kī ikaika kiʻekiʻe ma> M30, e hoʻohana i nā mea hao hao 45-gauge.

6. Hana ʻia nā wili hoʻopaʻa me 40Cr i hoʻopiʻi ʻia a hoʻonā.

7. Hoʻohana ʻia ke kila Q235B no ke kākoʻo, ka pā i hoʻopili ʻia, ke kākoʻo a me kāna mau ʻāpana pili.

8. Hana ʻia nā purlins i ke kila lahilahi i hana ʻia me ke kila Q235B.

9. Hanaʻia nā'ōpili maʻamau i nā bolts C-grade i hanaʻia me ke kila Q235 e kūpono ana i nā koi o ke kūlana aupuni o kēia manawa, aʻo ka helu hana he 4.8.

10. Pono nā māka kila i ʻōlelo ʻia ma luna nei i nā palapala hōʻoia maikaʻi a me nā hōʻike nānā hou, e like me nā koi o nā kūlana aupuni o kēia manawa.

11. Pono nā electrodes a me nā uea i hoʻohana ʻia no ke kuʻi ʻana i nā koi o nā kūlana aupuni o kēia manawa.Hoʻopili ʻia ma waena o nā kila Q235B e hoʻohana i nā electrodes moʻo E43.

12. ʻAʻole pono e ʻoi aku ka nui o ka waiwai i ana ʻia o ka ikaika hua i ka waiwai i ana ʻia o ka ikaika tensile o ke kila ma mua o 0.85.

13. Pono ke kila e loaʻa i nā ʻanuʻu hua ʻike, a ʻaʻole e emi ka elongation ma lalo o 20%.

14. Pono ke kila i ka weldability maikaʻi a me ka paʻakikī hopena kūpono.I ka wā he kila Q235B, pono e kūlike kona kūlana maikaʻi i ka "Carbon Structural Steel" (GB700-88), a inā ʻo Q355B, pono kona kūlana maikaʻi e kūlike me "Low Alloy High Strength Structural Steel" GB/T1491, pono nā kila a pau. loaʻa i ka ikaika tensile Ka hōʻoia hōʻoia no ka ikaika, elongation, yield strength, cold bending test and carbon, sulfur and phosphorus content.E loa'a nō ho'i i ka hale welded kahi hō'oia kūpono o ka ma'i kalapona.
