Krakatau Steel, melalui anak usahanya PT Krakatau Wajatama melakukan penandatanganan Joint Venture Agreement (JVA) dengan Natsteel Asia (s) Pte. Ltd dan PT Marubeni Itochu Steel Indonesia untuk mendirikan perusahaan patungan PT Krakatau Natsteel Construction Solution.

Direktur Utama Krakatau Steel Irvan Kamal Hakim mengatakan, pendirian perusahaan patungan ini merupakan bagian dari rencana pengembangan usaha PT Krakatau Wajatama, dalam mendukung pemenuhan kebutuhan produk prefabrikasi baja nasional. Perusahaan patungan tersebut akan menjadi pionir yang memberikan solusi total terhadap kebutuhan produk prefabrikasi baja di Indonesia (downstream steel products and services) dengan kapasitas produksi sebesar 70.000 ton per tahun.

“Perusahaan patungan ini diharapkan dapat memberi manfaat untuk menjadi pionir prefabrikasi baja di Indonesia, diversifikasi produk, peningkatan akses kepada state of the art technology & know how,” Direktur Utama Krakatau Steel.

Berlokasi di lahan seluas 13.720 M2 milik Krakatau Steel, di Cakung, Jakarta Timur, perusahaan patungan ini direncanakan memproduksi baja dengan spesifikasi yang ditujukan ke sektor konstruksi.

Pembentukan JV Co ini dimaksudkan untuk memenuhi kebutuhan prefabrikasi terkait pembangunan infrastruktur Indonesia yang sedang berkembang pesat, salah satunya adalah sarana transportasi massal (Mass Rapid Transport).

Modal dasar pendirian perusahaan patungan tahap pertama investasi sebesar US$ 2,2 juta, dengan modal ditempatkan dan disetor penuh perusahaan sebesar US$ 550 ribu. Untuk tahap awal, komposisi kepemilikan saham dari para pihak yang terlibat yakni Krakatau Wajatama sebesar 45%, Natsteel Asia (s) Pte. Ltd. Sebesar 45% serta PT. Marubeni Itochu Steel Indonesia sebesar 10%.

“Namun, ke depan modal dasar perusahaan patungan tersebut akan ditingkatkan pada investasi tahap II menjadi sebesar US$ 20 juta. Hal itu sebagai komitmen KS Group sebagai perusahaan baja terintegrasi hulu ke hilir,” tutup Irvan.

Jual Quard Abrasion Resistant Steel

Quard is a martesitic abrasion resistant steel, with an average hardness of 370 – 550 HBW. The steel offers very high resistance to abrasive wear and impact granting a longer service life. The combination of very good cold forming properties and excellent weldability makes Quard an optimal choice for most wear applications.

Quard 500 and 550 Viewmore »

Thickness: 8 – 20 mm
Width: 1500 – 2500 mm
Length: maximum 13 m

Welding Quard is easy and produces outstanding results.
Quard can be welded using any conventional welding method, both manually and automatically.
Due to the low carbon equivalents of Quard, preheating prior to welding is unnecessary in a thickness up to 20 mm.
On account of the tight thickness and flatness tolerances, Quard is well suited for automatic welding.
Quard can also be welded to any other weldable steel.


Quard has excellent cold forming properties, promoting new innovative solutions for lightweight design.

The excellent bending performance of Quard is achieved by:

  • low levels of non metallic inclusions
  • consistent mechanical properties
  • high crack resistance
  • tight thickness tolerances
  • excellent surface finish
  • consistent spring back
  • Numerous welding operations can be replaced by bending, resulting in a further reduction of production costs.


Thermal or cold cutting methods can be used for Quard steel.
Thermal cutting, using either oxygen fuel, plasma or laser cutting is as easy as cutting mild steel.
Quard does not require preheating prior to thermal cutting.
Cold cutting methods, such as abrasive water jet cutting, shearing or sawing have the advantages of not thermally affecting the part being cut, thus avoiding the softening of small parts being produced.

Quard can be machined in the same way as for any martensitic wear plates of the same hardness.
For drilling, either HSS (8%Co) or indexable cemented carbide drills can be used.
Face milling and countersinking best takes place using tools with replaceable cemented carbide inserts.
For all machining operations performed on Quard, stable machines should be used in order to keep tool set-up vibrations to a minimum.
